merging the per-bdi writeback patchset

[Jens Axboe <jens.axboe@oracle.com>]

Hi,

Things are looking good for this patchset and it's been in -next for
almost a week without any reports of problems. So I'd like to merge it
for 2.6.31 if at all possible. Any objections?

This was the last posting of the patchset:
