Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma
Pull rdma updates from Doug Ledford: "This is a fairly plain pull request. Lots of driver updates across the stack, a huge number of static analysis cleanups including a close to 50 patch series from Bart Van Assche, and a number of new features inside the stack such as general CQ moderation support. Nothing really stands out, but there might be a few conflicts as you take things in. In particular, the cleanups touched some of the same lines as the new timer_setup changes. Everything in this pull request has been through 0day and at least two days of linux-next (since Stephen doesn't necessarily flag new errors/warnings until day2). A few more items (about 30 patches) from Intel and Mellanox showed up on the list on Tuesday. I've excluded those from this pull request, and I'm sure some of them qualify as fixes suitable to send any time, but I still have to review them fully. If they contain mostly fixes and little or no new development, then I will probably send them through by the end of the week just to get them out of the way. There was a break in my acceptance of patches which coincides with the computer problems I had, and then when I got things mostly back under control I had a backlog of patches to process, which I did mostly last Friday and Monday. So there is a larger number of patches processed in that timeframe than I was striving for. Summary: - Add iWARP support to qedr driver - Lots of misc fixes across subsystem - Multiple update series to hns roce driver - Multiple update series to hfi1 driver - Updates to vnic driver - Add kref to wait struct in cxgb4 driver - Updates to i40iw driver - Mellanox shared pull request - timer_setup changes - massive cleanup series from Bart Van Assche - Two series of SRP/SRPT changes from Bart Van Assche - Core updates from Mellanox - i40iw updates - IPoIB updates - mlx5 updates - mlx4 updates - hns updates - bnxt_re fixes - PCI write padding support - Sparse/Smatch/warning cleanups/fixes - CQ moderation support - SRQ support in vmw_pvrdma" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma: (296 commits) RDMA/core: Rename kernel modify_cq to better describe its usage IB/mlx5: Add CQ moderation capability to query_device IB/mlx4: Add CQ moderation capability to query_device IB/uverbs: Add CQ moderation capability to query_device IB/mlx5: Exposing modify CQ callback to uverbs layer IB/mlx4: Exposing modify CQ callback to uverbs layer IB/uverbs: Allow CQ moderation with modify CQ iw_cxgb4: atomically flush the qp iw_cxgb4: only call the cq comp_handler when the cq is armed iw_cxgb4: Fix possible circular dependency locking warning RDMA/bnxt_re: report vlan_id and sl in qp1 recv completion IB/core: Only maintain real QPs in the security lists IB/ocrdma_hw: remove unnecessary code in ocrdma_mbx_dealloc_lkey RDMA/core: Make function rdma_copy_addr return void RDMA/vmw_pvrdma: Add shared receive queue support RDMA/core: avoid uninitialized variable warning in create_udata RDMA/bnxt_re: synchronize poll_cq and req_notify_cq verbs RDMA/bnxt_re: Flush CQ notification Work Queue before destroying QP RDMA/bnxt_re: Set QP state in case of response completion errors RDMA/bnxt_re: Add memory barriers when processing CQ/EQ entries ...
