Hi,
These are a set of patches [v5] which removes semaphores from infiniband.
These are part of a bigger effort to eliminate all semaphores from the
linux kernel.
v4 --> v5
---------
IB/isert: Replace semaphore sem with completion
- Modified changelog to support use of completion
IB/mlx5: Simplify completion into a wait_event
- Avoid this patch.
As umr_context is on the stack, and we are waiting
for it to be fully done, it really should be a completion.
v3 -> v4:
---------
IB/mlx5: Added patch - Replace semaphore umr_common:sem with wait_event
IB/mlx5: Fixed a bug pointed out by Leon Romanovsky
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
v1 -> v2:
---------
IB/hns : Use wait_event instead of open coding counting semaphores
IB/mthca : Use wait_event instead of open coding counting semaphores
IB/mthca : Remove mutex_[un]lock from *_cmd_use_events/*_cmd_use_polling
IB/mlx5 : Cleanup, add helper mlx5_ib_post_send_wait
v1
---------
IB/core: iwpm_nlmsg_request: Replace semaphore with completion
IB/core: Replace semaphore sm_sem with completion
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 condition
IB/mthca: Replace counting semaphore event_sem with wait condition
IB/mlx5: Replace counting semaphore sem with wait condition
Thanks,
Binoy
