From b896fb35ca904fe5b7765fcd81a45f09a62e8d03 Mon Sep 17 00:00:00 2001 From: "Dmitry V. Levin" Date: Thu, 19 Nov 2015 00:58:32 +0300 Subject: [PATCH] vfs: show_vfsstat: remove redundant initialization and check of error code As err variable is now always checked right after each assignment, its initialization is redundant and could be safely removed. For the same reason, the last check of err is also redundant and could be removed as well. Signed-off-by: Dmitry V.
