[PATCH rdma-next v1 0/4] ODP information and statistics

[Leon Romanovsky <leon@kernel.org>]

From: Leon Romanovsky <leonro@mellanox.com>

Changelog:
 v1:
 * Dropped umem patch, because it doesn't follow our IB model, where
   UMEM is driver object and ib_core object (Jason).
 * Removed the ODP type indicator from ib_umem_odp not needed after
   commit fd7dbf035edc ("RDMA/odp: Make it clearer when a umem is an implicit ODP umem")
 * Since umems are not part of core MR (from the reason mentioned
   above) there is no way to access the odp type as was previously done via nldev
   (old patch #3). Instead, patch #4 is adding mlx5 implementation for fill_res_entry
   and dumping ODP type as part of the driver table entry, as its driver details.
 * Counter types are now atomic64_t instead of u64.

Hi,

This series from Erez refactors exposes ODP type information (explicit,
implicit) and statistics through netlink interface.

Thanks

Erez Alfasi (4):
  IB/mlx5: Introduce ODP diagnostic counters
  RDMA/nldev: Allow different fill function per resource
  RDMA/nldev: Provide MR statistics
  RDMA/mlx5: Return ODP type per MR
