Subject: [PATCH v2 0/8] infiniband: Remove semaphores

Hi,

These are a set of patches [v2] which removes semaphores from infiniband.
These are part of a bigger effort to eliminate all semaphores from the
linux kernel.

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

Thanks,
Binoy
