Users who tried to use the ext4 file system driver is being used for the ext2 or ext3 file systems (via the CONFIG_EXT4_USE_FOR_EXT23 option) could have failed mounts if their /etc/fstab contains options recognized by ext2 or ext3 but which have since been removed in ext4. So teach ext4 to recognize them and give a warning that the mount option was removed.
