ext4: Rename ext4dev to ext4

The ext4 filesystem is getting stable enough that it's time to drop
the "dev" prefix.  Also remove the requirement for the TEST_FILESYS
flag.

-         Ext4dev is a predecessor filesystem of the next generation
-         extended fs ext4, based on ext3 filesystem code. It will be
-         renamed ext4 fs later, once ext4dev is mature and stabilized.
+         This is the next generation of the ext3 filesystem.
 
          Unlike the change from ext2 filesystem to ext3 filesystem,
-         the on-disk format of ext4dev is not the same as ext3 any more:
-         it is based on extent maps and it supports 48-bit physical block
-         numbers. These combined on-disk format changes will allow
-         ext4dev/ext4 to handle more than 16 TB filesystem volumes --
-         a hard limit that ext3 cannot overcome without changing the
-         on-disk format.
-
-         Other than extent maps and 48-bit block numbers, ext4dev also is
-         likely to have other new features such as persistent preallocation,
-         high resolution time stamps, and larger file support etc.  These
-         features will be added to ext4dev gradually.
+         the on-disk format of ext4 is not forwards compatible with
+         ext3; it is based on extent maps and it supports 48-bit
+         physical block numbers.  The ext4 filesystem also supports delayed
+         allocation, persistent preallocation, high resolution time stamps,
+         and a number of other features to improve performance and speed
+         up fsck time.  For more information, please see the web pages at
+         http://ext4.wiki.kernel.org.
+
+         The ext4 filesystem will support mounting an ext3
+         filesystem; while there will be some performance gains from
+         the delayed allocation and inode table readahead, the best
+         performance gains will require enabling ext4 features in the
+         filesystem, or formating a new filesystem as an ext4
+         filesystem initially.
 
          To compile this file system support as a module, choose M here. The
          module will be called ext4dev.
