Merge tag 'at24-4.16-updates-for-wolfram' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux into i2c/for-4.16
"AT24 updates for 4.16 merge window The driver has been converted to using regmap instead of raw i2c and smbus calls which shrank the code significantly. Device tree binding document has been cleaned up. Device tree support in the driver has been improved and we now support all at24 models as well as two new DT properties (no-read-rollover and wp-gpios). We no longer user unreadable magic values for driver data as the way it was implemented caused problems for some EEPROM models - we switched to regular structs. Aside from that, there's a bunch of coding style fixes and minor improvements all over the place."

-==========
-Background
-==========
-
-What causes deadlock
---------------------
-
-A deadlock occurs when a context is waiting for an event to happen,
-which is impossible because another (or the) context who can trigger the
-event is also waiting for another (or the) event to happen, which is
-also impossible due to the same reason.
-
-For example:
-
- A context going to trigger event C is waiting for event A to happen.
- A context going to trigger event A is waiting for event B to happen.
- A context going to trigger event B is waiting for event C to happen.
-
-A deadlock occurs when these three wait operations run at the same time,
-because event C cannot be triggered if event A does not happen, which in
-turn cannot be triggered if event B does not happen, which in turn
-cannot be triggered if event C does not happen. After all, no event can
-be triggered since any of them never meets its condition to wake up.
-
-A dependency might exist between two waiters and a deadlock might happen
-due to an incorrect releationship between dependencies. Thus, we must
-define what a dependency is first. A dependency exists between them if:
-
- 1. There are two waiters waiting for each event at a given time.
- 2. The only way to wake up each waiter is to trigger its event.
- 3. Whether one can be woken up depends on whether the other can.
-
-Each wait in the example creates its dependency like:
-
- Event C depends on event A.
- Event A depends on event B.
- Event B depends on event C.
-
- NOTE: Precisely speaking, a dependency is one between whether a
- waiter for an event can be woken up and whether another waiter for
- another event can be woken up. However from now on, we will describe
- a dependency as if it's one between an event and another event for
- simplicity.
-
-And they form circular dependencies like:
-
- -> C -> A -> B -
- / \
- \ /
- ----------------
-
- where 'A -> B' means that event A depends on event B.
-
-Such circular dependencies lead to a deadlock since no waiter can meet
-its condition to wake up as described.
-
-CONCLUSION
-
-Circular dependencies cause a deadlock.
-
-
-How lockdep works
------------------
-
-Lockdep tries to detect a deadlock by checking dependencies created by
-lock operations, acquire and release. Waiting for a lock corresponds to
-waiting for an event, and releasing a lock corresponds to triggering an
-event in the previous section.
-
-In short, lockdep does:
-
- 1. Detect a new dependency.
- 2. Add the dependency into a global graph.
- 3. Check if that makes dependencies circular.
- 4. Report a deadlock or its possibility if so.
-
-For example, consider a graph built by lockdep that looks like:
-
- A -> B -
- \
- -> E
- /
- C -> D -
-
- where A, B,..., E are different lock classes.
-
-Lockdep will add a dependency into the graph on detection of a new
-dependency. For example, it will add a dependency 'E -> C' when a new
-dependency between lock E and lock C is detected. Then the graph will be:
-
- A -> B -
- \
- -> E -
- / \
- -> C -> D - \
- / /
- \ /
- ------------------
-
- where A, B,..., E are different lock classes.
-
-This graph contains a subgraph which demonstrates circular dependencies:
-
- -> E -
- / \
- -> C -> D - \
- / /
- \ /
- ------------------
-
- where C, D and E are different lock classes.
-
-This is the condition under which a deadlock might occur. Lockdep
-reports it on detection after adding a new dependency. This is the way
-how lockdep works.
-
-CONCLUSION
-
-Lockdep detects a deadlock or its possibility by checking if circular
-dependencies were created after adding each new dependency.
-
-
-==========
-Limitation
-==========
-
-Limit lockdep
--------------
-
-Limiting lockdep to work on only typical locks e.g. spin locks and
-mutexes, which are released within the acquire context, the
-implementation becomes simple but its capacity for detection becomes
-limited. Let's check pros and cons in next section.
-
-
-Pros from the limitation
-------------------------
-
-Given the limitation, when acquiring a lock, locks in a held_locks
-cannot be released if the context cannot acquire it so has to wait to
-acquire it, which means all waiters for the locks in the held_locks are
-stuck. It's an exact case to create dependencies between each lock in
-the held_locks and the lock to acquire.
-
-For example:
-
- CONTEXT X
- ---------
- acquire A
- acquire B /* Add a dependency 'A -> B' */
- release B
- release A
-
- where A and B are different lock classes.
-
-When acquiring lock A, the held_locks of CONTEXT X is empty thus no
-dependency is added. But when acquiring lock B, lockdep detects and adds
-a new dependency 'A -> B' between lock A in the held_locks and lock B.
-They can be simply added whenever acquiring each lock.
-
-And data required by lockdep exists in a local structure, held_locks
-embedded in task_struct. Forcing to access the data within the context,
-lockdep can avoid racy problems without explicit locks while handling
-the local data.
-
-Lastly, lockdep only needs to keep locks currently being held, to build
-a dependency graph. However, relaxing the limitation, it needs to keep
-even locks already released, because a decision whether they created
-dependencies might be long-deferred.
-
-To sum up, we can expect several advantages from the limitation:
-
- 1. Lockdep can easily identify a dependency when acquiring a lock.
- 2. Races are avoidable while accessing local locks in a held_locks.
- 3. Lockdep only needs to keep locks currently being held.
-
-CONCLUSION
-
-Given the limitation, the implementation becomes simple and efficient.
-
-
-Cons from the limitation
-------------------------
-
-Given the limitation, lockdep is applicable only to typical locks. For
-example, page locks for page access or completions for synchronization
-cannot work with lockdep.
-
-Can we detect deadlocks below, under the limitation?
-
-Example 1:
-
- CONTEXT X CONTEXT Y CONTEXT Z
- --------- --------- ----------
- mutex_lock A
- lock_page B
- lock_page B
- mutex_lock A /* DEADLOCK */
- unlock_page B held by X
- unlock_page B
- mutex_unlock A
- mutex_unlock A
-
- where A and B are different lock classes.
-
-No, we cannot.
-
-Example 2:
-
- CONTEXT X CONTEXT Y
- --------- ---------
- mutex_lock A
- mutex_lock A
- wait_for_complete B /* DEADLOCK */
- complete B
- mutex_unlock A
- mutex_unlock A
-
- where A is a lock class and B is a completion variable.
-
-No, we cannot.
-
-CONCLUSION
-
-Given the limitation, lockdep cannot detect a deadlock or its
-possibility caused by page locks or completions.
-
-
-Relax the limitation
---------------------
-
-Under the limitation, things to create dependencies are limited to
-typical locks. However, synchronization primitives like page locks and
-completions, which are allowed to be released in any context, also
-create dependencies and can cause a deadlock. So lockdep should track
-these locks to do a better job. We have to relax the limitation for
-these locks to work with lockdep.
-
-Detecting dependencies is very important for lockdep to work because
-adding a dependency means adding an opportunity to check whether it
-causes a deadlock. The more lockdep adds dependencies, the more it
-thoroughly works. Thus Lockdep has to do its best to detect and add as
-many true dependencies into a graph as possible.
-
-For example, considering only typical locks, lockdep builds a graph like:
-
- A -> B -
- \
- -> E
- /
- C -> D -
-
- where A, B,..., E are different lock classes.
-
-On the other hand, under the relaxation, additional dependencies might
-be created and added. Assuming additional 'FX -> C' and 'E -> GX' are
-added thanks to the relaxation, the graph will be:
-
- A -> B -
- \
- -> E -> GX
- /
- FX -> C -> D -
-
- where A, B,..., E, FX and GX are different lock classes, and a suffix
- 'X' is added on non-typical locks.
-
-The latter graph gives us more chances to check circular dependencies
-than the former. However, it might suffer performance degradation since
-relaxing the limitation, with which design and implementation of lockdep
-can be efficient, might introduce inefficiency inevitably. So lockdep
-should provide two options, strong detection and efficient detection.
-
-Choosing efficient detection:
-
- Lockdep works with only locks restricted to be released within the
- acquire context. However, lockdep works efficiently.
-
-Choosing strong detection:
-
- Lockdep works with all synchronization primitives. However, lockdep
- suffers performance degradation.
-
-CONCLUSION
-
-Relaxing the limitation, lockdep can add additional dependencies giving
-additional opportunities to check circular dependencies.
-
-
-============
-Crossrelease
-============
-
-Introduce crossrelease
-----------------------
-
-In order to allow lockdep to handle additional dependencies by what
-might be released in any context, namely 'crosslock', we have to be able
-to identify those created by crosslocks. The proposed 'crossrelease'
-feature provoides a way to do that.
-
-Crossrelease feature has to do:
-
- 1. Identify dependencies created by crosslocks.
- 2. Add the dependencies into a dependency graph.
-
-That's all. Once a meaningful dependency is added into graph, then
-lockdep would work with the graph as it did. The most important thing
-crossrelease feature has to do is to correctly identify and add true
-dependencies into the global graph.
-
-A dependency e.g. 'A -> B' can be identified only in the A's release
-context because a decision required to identify the dependency can be
-made only in the release context. That is to decide whether A can be
-released so that a waiter for A can be woken up. It cannot be made in
-other than the A's release context.
-
-It's no matter for typical locks because each acquire context is same as
-its release context, thus lockdep can decide whether a lock can be
-released in the acquire context. However for crosslocks, lockdep cannot
-make the decision in the acquire context but has to wait until the
-release context is identified.
-
-Therefore, deadlocks by crosslocks cannot be detected just when it
-happens, because those cannot be identified until the crosslocks are
-released. However, deadlock possibilities can be detected and it's very
-worth. See 'APPENDIX A' section to check why.
-
-CONCLUSION
-
-Using crossrelease feature, lockdep can work with what might be released
-in any context, namely crosslock.
-
-
-Introduce commit
-----------------
-
-Since crossrelease defers the work adding true dependencies of
-crosslocks until they are actually released, crossrelease has to queue
-all acquisitions which might create dependencies with the crosslocks.
-Then it identifies dependencies using the queued data in batches at a
-proper time. We call it 'commit'.
-
-There are four types of dependencies:
-
-1. TT type: 'typical lock A -> typical lock B'
-
- Just when acquiring B, lockdep can see it's in the A's release
- context. So the dependency between A and B can be identified
- immediately. Commit is unnecessary.
-
-2. TC type: 'typical lock A -> crosslock BX'
-
- Just when acquiring BX, lockdep can see it's in the A's release
- context. So the dependency between A and BX can be identified
- immediately. Commit is unnecessary, too.
-
-3. CT type: 'crosslock AX -> typical lock B'
-
- When acquiring B, lockdep cannot identify the dependency because
- there's no way to know if it's in the AX's release context. It has
- to wait until the decision can be made. Commit is necessary.
-
-4. CC type: 'crosslock AX -> crosslock BX'
-
- When acquiring BX, lockdep cannot identify the dependency because
- there's no way to know if it's in the AX's release context. It has
- to wait until the decision can be made. Commit is necessary.
- But, handling CC type is not implemented yet. It's a future work.
-
-Lockdep can work without commit for typical locks, but commit step is
-necessary once crosslocks are involved. Introducing commit, lockdep
-performs three steps. What lockdep does in each step is:
-
-1. Acquisition: For typical locks, lockdep does what it originally did
- and queues the lock so that CT type dependencies can be checked using
- it at the commit step. For crosslocks, it saves data which will be
- used at the commit step and increases a reference count for it.
-
-2. Commit: No action is reauired for typical locks. For crosslocks,
- lockdep adds CT type dependencies using the data saved at the
- acquisition step.
-
-3. Release: No changes are required for typical locks. When a crosslock
- is released, it decreases a reference count for it.
-
-CONCLUSION
-
-Crossrelease introduces commit step to handle dependencies of crosslocks
-in batches at a proper time.
-
-
-==============
-Implementation
-==============
-
-Data structures
----------------
-
-Crossrelease introduces two main data structures.
-
-1. hist_lock
-
- This is an array embedded in task_struct, for keeping lock history so
- that dependencies can be added using them at the commit step. Since
- it's local data, it can be accessed locklessly in the owner context.
- The array is filled at the acquisition step and consumed at the
- commit step. And it's managed in circular manner.
-
-2. cross_lock
-
- One per lockdep_map exists. This is for keeping data of crosslocks
- and used at the commit step.
-
-
-How crossrelease works
-----------------------
-
-It's the key of how crossrelease works, to defer necessary works to an
-appropriate point in time and perform in at once at the commit step.
-Let's take a look with examples step by step, starting from how lockdep
-works without crossrelease for typical locks.
-
- acquire A /* Push A onto held_locks */
- acquire B /* Push B onto held_locks and add 'A -> B' */
- acquire C /* Push C onto held_locks and add 'B -> C' */
- release C /* Pop C from held_locks */
- release B /* Pop B from held_locks */
- release A /* Pop A from held_locks */
-
- where A, B and C are different lock classes.
-
- NOTE: This document assumes that readers already understand how
- lockdep works without crossrelease thus omits details. But there's
- one thing to note. Lockdep pretends to pop a lock from held_locks
- when releasing it. But it's subtly different from the original pop
- operation because lockdep allows other than the top to be poped.
-
-In this case, lockdep adds 'the top of held_locks -> the lock to acquire'
-dependency every time acquiring a lock.
-
-After adding 'A -> B', a dependency graph will be:
-
- A -> B
-
- where A and B are different lock classes.
-
-And after adding 'B -> C', the graph will be:
-
- A -> B -> C
-
- where A, B and C are different lock classes.
-
-Let's performs commit step even for typical locks to add dependencies.
-Of course, commit step is not necessary for them, however, it would work
-well because this is a more general way.
-
- acquire A
- /*
- * Queue A into hist_locks
- *
- * In hist_locks: A
- * In graph: Empty
- */
-
- acquire B
- /*
- * Queue B into hist_locks
- *
- * In hist_locks: A, B
- * In graph: Empty
- */
-
- acquire C
- /*
- * Queue C into hist_locks
- *
- * In hist_locks: A, B, C
- * In graph: Empty
- */
-
- commit C
- /*
- * Add 'C -> ?'
- * Answer the following to decide '?'
- * What has been queued since acquire C: Nothing
- *
- * In hist_locks: A, B, C
- * In graph: Empty
- */
-
- release C
-
- commit B
- /*
- * Add 'B -> ?'
- * Answer the following to decide '?'
- * What has been queued since acquire B: C
- *
- * In hist_locks: A, B, C
- * In graph: 'B -> C'
- */
-
- release B
-
- commit A
- /*
- * Add 'A -> ?'
- * Answer the following to decide '?'
- * What has been queued since acquire A: B, C
- *
- * In hist_locks: A, B, C
- * In graph: 'B -> C', 'A -> B', 'A -> C'
- */
-
- release A
-
- where A, B and C are different lock classes.
-
-In this case, dependencies are added at the commit step as described.
-
-After commits for A, B and C, the graph will be:
-
- A -> B -> C
-
- where A, B and C are different lock classes.
-
- NOTE: A dependency 'A -> C' is optimized out.
-
-We can see the former graph built without commit step is same as the
-latter graph built using commit steps. Of course the former way leads to
-earlier finish for building the graph, which means we can detect a
-deadlock or its possibility sooner. So the former way would be prefered
-when possible. But we cannot avoid using the latter way for crosslocks.
-
-Let's look at how commit steps work for crosslocks. In this case, the
-commit step is performed only on crosslock AX as real. And it assumes
-that the AX release context is different from the AX acquire context.
-

-
- where A, BX, C,..., E are different lock classes, and a suffix 'X' is
- added on crosslocks.
-
-Crossrelease considers all acquisitions after acqiuring BX are
-candidates which might create dependencies with BX. True dependencies
-will be determined when identifying the release context of BX. Meanwhile,
-all typical locks are queued so that they can be used at the commit step.
-And then two dependencies 'BX -> C' and 'BX -> E' are added at the
-commit step when identifying the release context.
-
-The final graph will be, with crossrelease:
-
- -> C
- /
- -> BX -
- / \
- A - -> E
- \
- -> D
-
- where A, BX, C,..., E are different lock classes, and a suffix 'X' is
- added on crosslocks.
-
-However, the final graph will be, without crossrelease:
-
- A -> D
-
- where A and D are different lock classes.
-
-The former graph has three more dependencies, 'A -> BX', 'BX -> C' and
-'BX -> E' giving additional opportunities to check if they cause
-deadlocks. This way lockdep can detect a deadlock or its possibility
-caused by crosslocks.
-
-CONCLUSION
-
-We checked how crossrelease works with several examples.
-
-
-=============
-Optimizations
-=============
-
-Avoid duplication
------------------
-
-Crossrelease feature uses a cache like what lockdep already uses for
-dependency chains, but this time it's for caching CT type dependencies.
-Once that dependency is cached, the same will never be added again.
-
-
-Lockless for hot paths
-----------------------
-
-To keep all locks for later use at the commit step, crossrelease adopts
-a local array embedded in task_struct, which makes access to the data
-lockless by forcing it to happen only within the owner context. It's
-like how lockdep handles held_locks. Lockless implmentation is important
-since typical locks are very frequently acquired and released.
-
-
-=================================================
-APPENDIX A: What lockdep does to work aggresively
-=================================================
-
-A deadlock actually occurs when all wait operations creating circular
-dependencies run at the same time. Even though they don't, a potential
-deadlock exists if the problematic dependencies exist. Thus it's
-meaningful to detect not only an actual deadlock but also its potential
-possibility. The latter is rather valuable. When a deadlock occurs
-actually, we can identify what happens in the system by some means or
-other even without lockdep. However, there's no way to detect possiblity
-without lockdep unless the whole code is parsed in head. It's terrible.
-Lockdep does the both, and crossrelease only focuses on the latter.
-
-Whether or not a deadlock actually occurs depends on several factors.
-For example, what order contexts are switched in is a factor. Assuming
-circular dependencies exist, a deadlock would occur when contexts are
-switched so that all wait operations creating the dependencies run
-simultaneously. Thus to detect a deadlock possibility even in the case
-that it has not occured yet, lockdep should consider all possible
-combinations of dependencies, trying to:
-
-1. Use a global dependency graph.
-
- Lockdep combines all dependencies into one global graph and uses them,
- regardless of which context generates them or what order contexts are
- switched in. Aggregated dependencies are only considered so they are
- prone to be circular if a problem exists.
-
-2. Check dependencies between classes instead of instances.
-
- What actually causes a deadlock are instances of lock. However,
- lockdep checks dependencies between classes instead of instances.
- This way lockdep can detect a deadlock which has not happened but
- might happen in future by others but the same class.
-
-3. Assume all acquisitions lead to waiting.
-
- Although locks might be acquired without waiting which is essential
- to create dependencies, lockdep assumes all acquisitions lead to
- waiting since it might be true some time or another.
-
-CONCLUSION
-
-Lockdep detects not only an actual deadlock but also its possibility,
-and the latter is more valuable.
-
-
-==================================================
-APPENDIX B: How to avoid adding false dependencies
-==================================================
-
-Remind what a dependency is. A dependency exists if:
-
- 1. There are two waiters waiting for each event at a given time.
- 2. The only way to wake up each waiter is to trigger its event.
- 3. Whether one can be woken up depends on whether the other can.
-
-For example:
-
- acquire A
- acquire B /* A dependency 'A -> B' exists */
- release B
- release A
-
- where A and B are different lock classes.
-
-A depedency 'A -> B' exists since:
-
- 1. A waiter for A and a waiter for B might exist when acquiring B.
- 2. Only way to wake up each is to release what it waits for.
- 3. Whether the waiter for A can be woken up depends on whether the
- other can. IOW, TASK X cannot release A if it fails to acquire B.
-
-For another example:
-
- TASK X TASK Y
- ------ ------
- acquire AX
- acquire B /* A dependency 'AX -> B' exists */
- release B
- release AX held by Y
-
- where AX and B are different lock classes, and a suffix 'X' is added
- on crosslocks.
-
-Even in this case involving crosslocks, the same rule can be applied. A
-depedency 'AX -> B' exists since:
-
- 1. A waiter for AX and a waiter for B might exist when acquiring B.
- 2. Only way to wake up each is to release what it waits for.
- 3. Whether the waiter for AX can be woken up depends on whether the
- other can. IOW, TASK X cannot release AX if it fails to acquire B.
-
-Let's take a look at more complicated example:
-
- TASK X TASK Y
- ------ ------
- acquire B
- release B
- fork Y
- acquire AX
- acquire C /* A dependency 'AX -> C' exists */
- release C
- release AX held by Y
-
- where AX, B and C are different lock classes, and a suffix 'X' is
- added on crosslocks.
-
-Does a dependency 'AX -> B' exist? Nope.
-
-Two waiters are essential to create a dependency. However, waiters for
-AX and B to create 'AX -> B' cannot exist at the same time in this
-example. Thus the dependency 'AX -> B' cannot be created.
-
-It would be ideal if the full set of true ones can be considered. But
-we can ensure nothing but what actually happened. Relying on what
-actually happens at runtime, we can anyway add only true ones, though
-they might be a subset of true ones. It's similar to how lockdep works
-for typical locks. There might be more true dependencies than what
-lockdep has detected in runtime. Lockdep has no choice but to rely on
-what actually happens. Crossrelease also relies on it.
-
-CONCLUSION
-
-Relying on what actually happens, lockdep can avoid adding false
-dependencies.

+The scsi_device structure has had reference counting infrastructure added.
+This effectively spreads the ownership of struct scsi_device instances

use scsi_device_put() to decrement its reference count (and potentially
delete it).
