7 Ext2 is a standard Linux file system for hard disks.

9 This filesystem driver is deprecated because it does not properly
10 support inode time stamps beyond 03:14:07 UTC on 19 January 2038.
11
12 Ext2 users are advised to use ext4 driver to access their filesystem.
13 The driver is fully compatible, supports filesystems without journal
14 or extents, and also supports larger time stamps if the filesystem
15 is created with at least 256 byte inodes.

17 This code is kept as a simple reference for filesystem developers.

44 Security labels support alternative access control models
45 implemented by security modules like SELinux. This option
46 enables an extended attribute handler for file security
47 labels in the ext2 filesystem.

49 If you are not using a security module that requires using
50 extended attributes for file security labels, say N.
