Subject: [PATCH rdma-next 0/3] Delay mlx5_ib internal resources allocations

From: Leon Romanovsky <leonro@...dia.com>

Internal mlx5_ib resources are created during mlx5_ib module load. This
behavior is not optimal because it consumes resources that are not
needed when SFs are created. This patch series delays the creation of
mlx5_ib internal resources to the stage when they actually used.

Thanks

  net/mlx5: Reimplement write combining test
  IB/mlx5: Create UMR QP just before first reg_mr occurs
  IB/mlx5: Allocate resources just before first QP/SRQ is created
