          Ext2 is a standard Linux file system for hard disks.
 
-         To compile this file system support as a module, choose M here: the
-         module will be called ext2.
+         This filesystem driver is deprecated because it does not properly
+         support inode time stamps beyond 03:14:07 UTC on 19 January 2038.
 
-         If unsure, say Y.
+         Ext2 users are advised to use ext4 driver to access their filesystem.
+         The driver is fully compatible, supports filesystems without journal
+          or extents, and also supports larger time stamps if the filesystem
+          is created with at least 256 byte inodes.
+
+         This code is kept as a simple reference for filesystem developers.
+
+         If unsure, say N.
