ext4: drop ext4dev compat 



Kconfig & super.c promised it'd be gone by 2.6.31, so it's
about time to drop it.

	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!
