Subject: [PATCH 0/9] Per-bdi writeback flusher threads v13
Date: Thu, 30 Jul 2009 23:23:55 +0200	[thread overview]
Message-ID: <1248989044-21605-1-git-send-email-jens.axboe@oracle.com> (raw)

Hi,

Here's the 13th version of the writeback patches. Changes since v12:

- Update to 2.6.31-rc4 ('ish, it's on top of current -git, but wil apply
  to -rc4 as well).
- Drop the last patch in the series, it was a questionable optimization
  that needs to be tested and evaluated separately.

For ease of patching, I've put the full diff here:

  http://kernel.dk/writeback-v13.patch

and also stored this in a writeback-v12 branch that will not change,
you can pull that into Linus tree from here:

  git://git.kernel.dk/linux-2.6-block.git writeback-v13

I'm not aware of any problems with this code at this point, and it's
been sitting in -next for a few months without reported incidents.
The target for the patchset is still 2.6.32.
