ext4: fix ext4_show_options for file systems w/o journal
Instead of removing EXT4_MOUNT_JOURNAL_CHECKSUM from s_def_mount_opt as I assume was intended, all other options were blown away leading to _ext4_show_options() output being incorrect. Fixes: 1e381f60dad9 ("ext4: do not allow journal_opts for fs w/o journal") Signed-off-by: Debabrata Banerjee <dbanerje@akamai.com> Signed-off-by: Theodore Ts'o <tytso@mit.edu> Reviewed-by: Jan Kara <jack@suse.cz> Cc: stable@kernel.org
