Merge branch 'for-5.13' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup
Pull cgroup changes from Tejun Heo: "The only notable change is Vipin's new misc cgroup controller. This implements generic support for resources which can be controlled by simply counting and limiting the number of resource instances - ie there's X number of these on the system and this cgroup subtree can have upto Y of those. The first user is the address space IDs used for virtual machine memory encryption and expected future usages are similar - niche hardware features with concrete resource limits and simple usage models" * 'for-5.13' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup: cgroup: use tsk->in_iowait instead of delayacct_is_task_waiting_on_io() cgroup/cpuset: fix typos in comments cgroup: misc: mark dummy misc_cg_res_total_usage() static inline svm/sev: Register SEV and SEV-ES ASIDs to the misc controller cgroup: Miscellaneous cgroup documentation. cgroup: Add misc cgroup controller

+ Provides a controller for miscellaneous resources on a host.
+
+ Miscellaneous scalar resources are the resources on the host system
+ which cannot be abstracted like the other cgroups. This controller
+ tracks and limits the miscellaneous resources used by a process
+ attached to a cgroup hierarchy.
+
+ For more information, please check misc cgroup section in
