Subject: [PATCH rdma-next 0/5] Reorganize mlx5 UMR creation flow
Date: Mon, 14 Sep 2020 14:26:48 +0300 [thread overview]
Message-ID: <20200914112653.345244-1-leon@kernel.org> (raw)
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
