If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit ccc1860dc72fd2fca77261a6acc8ae90e91b0ff1 Author: Eric Biggers <ebiggers@xxxxxxxxxx> Date: Tue May 10 11:32:32 2022 -0700 ext4: reject the 'commit' option on ext2 filesystems [ Upstream commit cb8435dc8ba33bcafa41cf2aa253794320a3b8df ] The 'commit' option is only applicable for ext3 and ext4 filesystems, and has never been accepted by the ext2 filesystem driver, so the ext4 driver shouldn't allow it on ext2 filesystems. This fixes a failure in xfstest ext4/053.
