Alexey Dobriyan 6da0b38f44 fs/Kconfig: move ext2, ext3, ext4, JBD, JBD2 out
Use fs/*/Kconfig more, which is good because everything related to one
filesystem is in one place and fs/Kconfig is quite fat.

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.
