[PATCH 0/2] xfs: patches for 3.2

[Dave Chinner]

These are the two patches I have outstanding for 3.2. I've dropped
the xfsbufd changes from the series as Christoph and I have been
discussing ways to change metadata writeback that make the xfsbufd
redundant. Hence there's no need to change it now...

I've dropped all the interface changes from the xfs buf allocation
code change, simplifying it lots, and fixed the problems reported
with it. I've also fixed a bug in the AIL log force reduction patch
that caused the AIL to get stuck when pinned buffers caused the
stuck processing to loop.
