+config EXT3_FS
+ tristate "Ext3 journalling file system support"
+ select JBD
+ 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.
+
+config EXT3_FS_XATTR
+ bool "Ext3 extended attributes"
+ depends on EXT3_FS
+ default y
+ 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.
+
+config EXT3_FS_POSIX_ACL
+ bool "Ext3 POSIX Access Control Lists"
+ depends on EXT3_FS_XATTR
+ select FS_POSIX_ACL
+ 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
+ bool "Ext3 Security Labels"
+ depends on EXT3_FS_XATTR
+ 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.
