From: Leon Romanovsky <leonro@xxxxxxxxxxxx> Hi, This are three patches which I would ask to consider for current PR to Linus. First two patches are fixing corner cases that are not possible in the real life and the third patch is needed to ensure that API toward user space is feature complete and won't need any extra ucontext flags. The code of third patch was already presented in v0 and v1, but was dropped later. Leon Romanovsky (3): RDMA/mlx5: Return an error if copy_to_user fails RDMA/mlx5: Don't rely on FW to set zeros in ECE response RDMA/mlx5: Return ECE DC support drivers/infiniband/hw/mlx5/qp.c | 59 +++++++++++++++++++++------------ include/linux/mlx5/mlx5_ifc.h | 5 +-- 2 files changed, 40 insertions(+), 24 deletions(-) -- 2.26.2
