+         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.
+
+         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.
+
+         To compile this file system support as a module, choose M here. The
+         module will be called ext4dev.  Be aware, however, that the filesystem
+         of your root partition (the one containing the directory /) cannot
+         be compiled as a module, and so this could be dangerous.
