You can always try the reverse - replace fs/xfs from your mips build
tree with the one from the current/a recent kernel.  Theres very few
changes in the surrounding kernel code that xfs needs.

Eric should be able to comment on the pitfalls in doing this having
tried to backport a 2.6.25 fs/xfs to a 2.6.18 RHEL kernel. Eric -
any comments?

Cheers,

Dave.
Eric, Could you please let me know about bits and pieces that we need to remember while back porting xfs to 2.6.18?
If you share patches which takes care of it, that would be great.

Thanks
Sagar
