Subject: [PATCH rdma-next 00/12] Refactor UMR post send logic

From: Leon Romanovsky <leonro@...dia.com>

Hi,

UMR are special QPs that require slightly different logic than other
QPs. This series from Aharon refactors the logic around UMR QP to
separate file and functions to clean the post send flow.

Thanks

Aharon Landau (12):
  RDMA/mlx5: Move init and cleanup of UMR to umr.c
  RDMA/mlx5: Move umr checks to umr.h
  RDMA/mlx5: Move mkey ctrl segment logic to umr.c
  RDMA/mlx5: Simplify get_umr_update_access_mask()
  RDMA/mlx5: Expose wqe posting helpers outside of wr.c
  RDMA/mlx5: Introduce mlx5_umr_post_send_wait()
  RDMA/mlx5: Use mlx5_umr_post_send_wait() to revoke MRs
  RDMA/mlx5: Use mlx5_umr_post_send_wait() to rereg pd access
  RDMA/mlx5: Move creation and free of translation tables to umr.c
  RDMA/mlx5: Use mlx5_umr_post_send_wait() to update MR pas
  RDMA/mlx5: Use mlx5_umr_post_send_wait() to update xlt
  RDMA/mlx5: Clean UMR QP type flow from mlx5_ib_post_send()
