The crash was caused by a variable being erronously declared static in token2str(). In addition to /proc/mounts, the problem can also be easily replicated by accessing /proc/fs/ext4/<partition>/options in parallel: $ cat /proc/fs/ext4/<partition>/options > options.txt ... and then running the following command in two different terminals: $ while diff /proc/fs/ext4/<partition>/options options.txt; do true; done This is also the cause of the following a crash while running xfstests #234, as reported in the following bug reports: https://bugs.launchpad.net/bugs/1053019 https://bugzilla.kernel.org/show_bug.cgi?id=47731Signed-off-by: Herton Ronaldo Krzesinski <herton.krzesinski@canonical.com> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu> Cc: Brad Figg <brad.figg@canonical.com> Cc: stable@vger.kernel.org
