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 <http://oss.sgi.com/projects/xfs/>
for complete details. This implementation is on-disk compatible
with the IRIX version of XFS.

To compile this file system support as a module, choose M here: the
module will be called xfs. Be aware, however, that if the file
system of your root partition is compiled as a module, you'll need
to use an initial ramdisk (initrd) to boot.
