75 This is the journalling version of the Second extended file system
76 (often called ext3), the de facto standard Linux file system
77 (method to organize files on a storage device) for hard disks.
78
79 The journalling code included in this driver means you do not have
80 to run e2fsck (file system checker) on your file systems after a
81 crash. The journal keeps track of any changes that were being made
82 at the time the system crashed, and can ensure that your file system
83 is consistent without the need for a lengthy check.
84
85 Other than adding the journal to the file system, the on-disk format
86 of ext3 is identical to ext2. It is possible to freely switch
87 between using the ext3 driver and the ext2 driver, as long as the
88 file system has been cleanly unmounted, or e2fsck is run on the file
89 system.
90
91 To add a journal on an existing ext2 file system or change the
92 behavior of ext3 file systems, you can use the tune2fs utility ("man
93 tune2fs"). To modify attributes of files and directories on ext3
94 file systems, use chattr ("man chattr"). You need to be using
95 e2fsprogs version 1.20 or later in order to create ext3 journals
96 (available at <http://sourceforge.net/projects/e2fsprogs/>).

146 Unlike the change from ext2 filesystem to ext3 filesystem,
147 the on-disk format of ext4 is not forwards compatible with

154
155 The ext4 filesystem will support mounting an ext3
156 filesystem; while there will be some performance gains from
