[GIT PULL] xfs: Use bulk page allocator for buffer cache

[GIT PULL] xfs: Use bulk page allocator for buffer cache

[Dave Chinner]

Hi Darrick,

Please pull the reviewed series from the signed tag detailed below.
This has been updated with all the latested RVB tags and the couple
of typos/whitespace issues you noticed when reviewing it. The branch
is based on linux-xfs/master, and merges cleanly into the current
for-next branch.

I sent a pull-req rather than posting the series again just for rvb
updates as we already have enough noise on the list. Let me know if
you would prefer patches over pull requests, or whether you want
more information in the tags in future (e.g. series description for
the merge commit) or anything else like that.

Cheers,

Dave.

Would you mind pushing a new tag containing the cover letter for the
series so that we can capture that in the git history?
