Btw, Redhat has a completely different XFS codebase than mainline
2.6.32, here's the diffstat summary between 2.6.32 and rhel6.1:

 96 files changed, 5083 insertions(+), 5211 deletions(-)

Which roughly equals the diff between 2.6.32 and 2.6.34.  So there's
a fairly large chance things simply won't apply as-is anyway.  The same
is also true for ext4, btrfs and nfs.
