From 20ec0a6d6016aa28b9b3299be18baef1a0f91cd2 Mon Sep 17 00:00:00 2001 From: Xiao Yang Date: Mon, 21 Jun 2021 15:14:56 +0800 Subject: [PATCH] RDMA/rxe: Don't overwrite errno from ib_umem_get() rxe_mr_init_user() always returns the fixed -EINVAL when ib_umem_get() fails so it's hard for user to know which actual error happens in ib_umem_get(). For example, ib_umem_get() will return -EOPNOTSUPP when trying to pin pages on a DAX file. Return actual error as mlx4/mlx5 does.
