From eab450789829e33a64dbd08dced3438d580d5179 Mon Sep 17 00:00:00 2001 From: Phil Sutter Date: Thu, 24 Aug 2017 11:51:46 +0200 Subject: [PATCH] lib/fs: Fix format string in find_fs_mount() A field width of 4096 allows fscanf() to store that amount of characters into the given buffer, though that doesn't include the terminating NULL byte. Decrease the value by one to leave space for it.
