Subject: [PATCH] ext4: drop ext4dev compat
Kconfig & super.c promised it'd be gone by 2.6.31, so it's
about time to drop it.

- 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!
