#     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"
