Yet another patch question

[David Chambers <davidc@xxxxxxxxxxxxx>]

While we are(were!) on the subject of patches, has anyone successfully
applied the XFS patch to a rmap12a patched kernel?  (or vice versa)

Is this even a sane thing to try (okay, no)?  I tried yesterday but the
few rejects there are look 'orrible - I'm not that good a hacker to
figure them out...
