Ext2 is a standard Linux file system for hard disks.
config ADK_KERNEL_EXT3_FS
tristate "EXT3 filesystem support"
select ADK_KERNEL_BLOCK
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 ).

If you say Y here, you will be able to mount extended format
Macintosh-formatted hard drive partitions with full read-write access.
This file system is often called HFS+ and was introduced with
MacOS 8. It includes all Mac specific filesystem data such as
data forks and creator codes, but it also has several UNIX
style features such as file ownership and permissions.
config ADK_KERNEL_NTFS_FS
tristate "NTFS file system support"
select ADK_KERNEL_BLOCK
help
NTFS is the file system of Microsoft Windows NT, 2000, XP and 2003.
Saying Y or M here enables read support. There is partial, but
safe, write support available. For write support you must also
say Y to "NTFS write support" below.
There are also a number of user-space tools available, called
ntfsprogs. These include ntfsundelete and ntfsresize, that work
without NTFS support enabled in the kernel.
This is a rewrite from scratch of Linux NTFS support and replaced
the old NTFS code starting with Linux 2.5.11. A backport to
the Linux 2.4 kernel series is separately available as a patch
from the project web site.
For more information see
and .
If you are not using Windows NT, 2000, XP or 2003 in addition to
Linux on your computer it is safe to say N.

This option provides support for normal Windows file systems with
long filenames. That includes non-compressed FAT-based file systems
used by Windows 95, Windows 98, Windows NT 4.0, and the Unix
programs from the mtools package.
The VFAT support enlarges your kernel by about 10 KB Please read the
file for details.

XFS is a high performance journaling filesystem which originated
on the SGI IRIX platform. It is completely multi-threaded, can
support large files and large filesystems, extended attributes,
variable block sizes, is extent based, and makes extensive use of
Btrees (directories, extents, free space) to aid both performance
and scalability.
Refer to the documentation at
for complete details. This implementation is on-disk compatible
with the IRIX version of XFS.

Btrfs is a general purpose copy-on-write filesystem with extents,
writable snapshotting, support for multiple devices and many more
features focused on fault tolerance, repair and easy administration.

config ADK_KERNEL_FUSE_FS
tristate "Filesystem in Userspace support"
help
With FUSE it is possible to implement a fully functional
filesystem in a userspace program.
By enabling this, only the kernel module gets build.
For using it, you will most likely also want to enable
fuse-utils.

This is the standard file system used on CD-ROMs. It was previously
known as "High Sierra File System" and is called "hsfs" on other
Unix systems. The so-called Rock-Ridge extensions which allow for
long Unix filenames and symbolic links are also supported by this
driver. If you have a CD-ROM drive and want to do more with it than
just listen to audio CDs and watch its LEDs, say Y (and read
and the CD-ROM-HOWTO,
available from ), thereby
enlarging your kernel by about 27 KB; otherwise say N.
