From 4cab7debf3e05a6a2411c1b0192d849190be79a6 Mon Sep 17 00:00:00 2001 From: Eli Cohen Date: Mon, 6 Feb 2023 14:19:56 +0200 Subject: [PATCH] vdpa/mlx5: Don't clear mr struct on destroy MR [ Upstream commit aef24311bd2d8a6d39a80c34f278b0fd1692aed3 ] 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.
