Use fs/*/Kconfig more, which is good because everything related to one filesystem is in one place and fs/Kconfig is quite fat. Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

help
|
|
This is the journalling version of the Second extended file system
|
|
(often called ext3), the de facto standard Linux file system
|
|
(method to organize files on a storage device) for hard disks.
|
|
|
|
The journalling code included in this driver means you do not have
|
|
to run e2fsck (file system checker) on your file systems after a
|
|
crash. The journal keeps track of any changes that were being made
|
|
at the time the system crashed, and can ensure that your file system
|
|
is consistent without the need for a lengthy check.
|
|
|
|
Other than adding the journal to the file system, the on-disk format
|
|
of ext3 is identical to ext2. It is possible to freely switch
|
|
between using the ext3 driver and the ext2 driver, as long as the
|
|
file system has been cleanly unmounted, or e2fsck is run on the file
|
|
system.
|
|
|
|
To add a journal on an existing ext2 file system or change the
|
|
behavior of ext3 file systems, you can use the tune2fs utility ("man
|
|
tune2fs"). To modify attributes of files and directories on ext3
|
|
file systems, use chattr ("man chattr"). You need to be using
|
|
e2fsprogs version 1.20 or later in order to create ext3 journals
|
|
(available at <http://sourceforge.net/projects/e2fsprogs/>).
|
|
|
|
To compile this file system support as a module, choose M here: the
|
|
module will be called ext3.

help
|
|
Extended attributes are name:value pairs associated with inodes by
|
|
the kernel or by users (see the attr(5) manual page, or visit
|
|
<http://acl.bestbits.at/> for details).
|
|
|
|
If unsure, say N.

You need this for POSIX ACL support on ext3.

help
|
|
Posix Access Control Lists (ACLs) support permissions for users and
|
|
groups beyond the owner/group/world scheme.
|
|
|
|
To learn more about Access Control Lists, visit the Posix ACLs for
|
|
Linux website <http://acl.bestbits.at/>.
|

If you don't know what Access Control Lists are, say N

config EXT3_FS_SECURITY

|
|
help
|
|
Security labels support alternative access control models
|
|
implemented by security modules like SELinux. This option
|
|
enables an extended attribute handler for file security
|
|
labels in the ext3 filesystem.
|
|
|
|
If you are not using a security module that requires using
|
|
extended attributes for file security labels, say N.
