ext4: drop fast_commit from /proc/mounts
The options in /proc/mounts must be valid mount options --- and fast_commit is not a mount option. Otherwise, command sequences like this will fail: # mount /dev/vdc /vdc # mkdir -p /vdc/phoronix_test_suite /pts # mount --bind /vdc/phoronix_test_suite /pts # mount -o remount,nodioread_nolock /pts mount: /pts: mount point not mounted or bad option. And in the system logs, you'll find: EXT4-fs (vdc): Unrecognized mount option "fast_commit" or missing value Fixes: 995a3ed67fc8 ("ext4: add fast_commit feature and handling for extended mount options") Signed-off-by: Theodore Ts'o <tytso@mit.edu>
