Personally, I would not use xfs on Linux ... maybe take a look here:

http://distrowatch.com/weekly.php?issue=20060814

And see what several debain devel's say about XFS.

RedHat says it is not stable enough to use in RHEL.

I don't think everyone can be wrong.

If you really want to use it, you can use the module you referenced
above and our kernel.  The standard RHEL kernel will not compile w/
anything except 4k stacks (that is how the CentOS kernel is released
too) ... so if you want to do that, you'll need to figure it out.
