From 153ee1c41a3ec707438ae0ca6b0061f72de334ef Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Wed, 19 Jan 2022 18:08:06 -0800 Subject: [PATCH] sysctl: fix duplicate path separator in printed entries sysctl_print_dir() always terminates the printed path name with a slash, so printing a slash before the file part causes a duplicate like in sysctl duplicate entry: /kernel//perf_user_access Fix this by dropping the extra slash.
