Subject: [PATCH 1/2] vdpa/mlx5: Don't clear mr struct on destroy MR
Date: Mon, 6 Feb 2023 14:19:56 +0200 [thread overview]
Message-ID: <20230206121956.1149356-1-elic@nvidia.com> (raw)
Clearing the mr struct erases the lock owner and causes warnings to be
emitted. It is not required to clear the mr so remove the memset call.
Fixes: 94abbccdf291 ("vdpa/mlx5: Add shared memory registration code")
Signed-off-by: Eli Cohen <elic@nvidia.com>
