[PATCH rdma-next 0/5] Reorganize mlx5 UMR creation flow

[Leon Romanovsky]

From: Leon Romanovsky <leonro@nvidia.com>

This flow has become crufty and confusing. Revise it so that the rules
on how UMR is used with MRs is much clearer and more correct.

Fixes a few minor bugs in ODP and rereg_mr where disallowed things were
not properly blocked.

Thanks

Jason Gunthorpe (5):
  RDMA/mlx5: Remove dead check for EAGAIN after alloc_mr_from_cache()
  RDMA/mlx5: Use set_mkc_access_pd_addr_fields() in reg_create()
  RDMA/mlx5: Make mkeys always owned by the kernel's PD when not enabled
  RDMA/mlx5: Disable IB_DEVICE_MEM_MGT_EXTENSIONS if IB_WR_REG_MR can't
    work
  RDMA/mlx5: Clarify what the UMR is for when creating MRs
