Christoph, I'd better give you a progress report, to avoid another mail
as foul as was sent after yours.

I wonder what the fuss is: Matthew (thank you) has been giving excellent
reviews, and mm is a cooperative not a dickinstatorship (but I was upset
that he caught that GFP_HIGHUSER, which I had been eager to point out).

I haven't finished yet, but made good progress and it does look good:
a few very minor comments so far, nothing that couldn't be patched up
later if that suits you best.

mm.git contains no updates to mm/shmem.c yet this cycle, so I expect
that Andrew will be fine with the series going in via the XFS tree,
unless some awkward conflict in one of the mm files appears.

Tomorrow,
Hugh
