-        help
-          Starting with 2.6.28, the name of the ext4 filesystem was
-          renamed from ext4dev to ext4.  Unfortunately there are some
-          legacy userspace programs (such as klibc's fstype) have
-          "ext4dev" hardcoded.
-
-          To enable backwards compatibility so that systems that are
-          still expecting to mount ext4 filesystems using ext4dev,
-          choose Y here.   This feature will go away by 2.6.31, so
-          please arrange to get your userspace programs fixed!
