[PATCH rdma-next 0/5] Use ib_umem_find_best_pgsz() when creating MRs

[PATCH rdma-next 0/5] Use ib_umem_find_best_pgsz() when creating MRs

[Leon Romanovsky]

From: Leon Romanovsky <leonro@nvidia.com>

From Jason:

The new common code does a better job finding large page sizes. Use it in
mlx5 for MRs.

This requires moving the MTT population for mailboxes and UMR over to
rdma_for_each_dma_block().

Thanks

Jason Gunthorpe (5):
  RDMA/mlx5: Change mlx5_ib_populate_pas() to use rdma_for_each_block()
  RDMA/mlx5: Move xlt_emergency_page_mutex into mr.c
  RDMA/mlx5: Split the WR setup out of mlx5_ib_update_xlt()
  RDMA/mlx5: Split mlx5_ib_update_xlt() into ODP and non-ODP cases
  RDMA/mlx5: Use ib_umem_find_best_pgsz() for mkc's

Applied to for-next, with the updated hunk

Thanks,
