This series moves the MR cache to use RB tree to store the entries of the cache. By doing so, enabling more flexibility when managing the cache entries. The MR cache will now cache mkeys returned by the user even if they are not from one of the predefined pools, by that allowing restarting applications to reuse the their released mkey and improve restart times. v0->v1: - Fix rb tree search from memcmp to dedicated cmp function - Rewording of some commit messages Aharon Landau (8): RDMA/mlx5: Don't keep umrable 'page_shift' in cache entries RDMA/mlx5: Generalize mlx5_cache_cache_mr() to fit all cacheable mkeys RDMA/mlx5: Remove explicit ODP cache entry RDMA/mlx5: Allow rereg all the mkeys that can load pas with UMR RDMA/mlx5: Introduce mlx5r_cache_rb_key RDMA/mlx5: Change the cache structure to an RB-tree RDMA/mlx5: Cache all user cacheable mkeys on dereg MR flow RDMA/mlx5: Add work to remove temporary entries from the cache drivers/infiniband/hw/mlx5/mlx5_ib.h | 42 +- drivers/infiniband/hw/mlx5/mr.c | 574 ++++++++++++++++++++------- drivers/infiniband/hw/mlx5/odp.c | 34 +- include/linux/mlx5/driver.h | 1 - 4 files changed, 465 insertions(+), 186 deletions(-) -- 2.17.2
