Subject: [PATCH v3 0/9] infiniband: Remove semaphores

Hi,

These are a set of patches [v3] which removes semaphores from infiniband.
These are part of a bigger effort to eliminate all semaphores from the
linux kernel.

v2 -> v3:

IB/mlx5: Move '&umr_context' into helper fn
IB/mthca: Restructure mthca_cmd.c to manage free_head
IB/hns: Restructure hns_roce_cmd.c to manage free_head
IB/core: Convert completion to wait_event
IB/mlx5: Simplify completion into a wait_event


Thanks,
Binoy

  IB/core: iwpm_nlmsg_request: Replace semaphore with completion
  IB/core: Replace semaphore sm_sem with an atomic wait
  IB/hns: Replace semaphore poll_sem with mutex
  IB/mthca: Replace semaphore poll_sem with mutex
  IB/isert: Replace semaphore sem with completion
  IB/hns: Replace counting semaphore event_sem with wait_event
  IB/mthca: Replace counting semaphore event_sem with wait_event
  IB/mlx5: Add helper mlx5_ib_post_send_wait
  IB/mlx5: Simplify completion into a wait_event
