Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma
Pull rdma updates from Jason Gunthorpe: "The majority of the patches are cleanups, refactorings and clarity improvements. This cycle saw some more activity from Syzkaller, I think we are now clean on all but one of those bugs, including the long standing and obnoxious rdma_cm locking design defect. Continue to see many drivers getting cleanups, with a few new user visible features. Summary: - Various driver updates for siw, bnxt_re, rxe, efa, mlx5, hfi1 - Lots of cleanup patches for hns - Convert more places to use refcount - Aggressively lock the RDMA CM code that syzkaller says isn't working - Work to clarify ib_cm - Use the new ib_device lifecycle model in bnxt_re - Fix mlx5's MR cache which seems to be failing more often with the new ODP code - mlx5 'dynamic uar' and 'tx steering' user interfaces" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma: (144 commits) RDMA/bnxt_re: make bnxt_re_ib_init static IB/qib: Delete struct qib_ivdev.qp_rnd RDMA/hns: Fix uninitialized variable bug RDMA/hns: Modify the mask of QP number for CQE of hip08 RDMA/hns: Reduce the maximum number of extend SGE per WQE RDMA/hns: Reduce PFC frames in congestion scenarios RDMA/mlx5: Add support for RDMA TX flow table net/mlx5: Add support for RDMA TX steering IB/hfi1: Call kobject_put() when kobject_init_and_add() fails IB/hfi1: Fix memory leaks in sysfs registration and unregistration IB/mlx5: Move to fully dynamic UAR mode once user space supports it IB/mlx5: Limit the scope of struct mlx5_bfreg_info to mlx5_ib IB/mlx5: Extend QP creation to get uar page index from user space IB/mlx5: Extend CQ creation to get uar page index from user space IB/mlx5: Expose UAR object and its alloc/destroy commands IB/hfi1: Get rid of a warning RDMA/hns: Remove redundant judgment of qp_type RDMA/hns: Remove redundant assignment of wc->smac when polling cq RDMA/hns: Remove redundant qpc setup operations RDMA/hns: Remove meaningless prints ...
