Subject: [PATCH 0/10] Per-bdi writeback flusher threads v11
Hi,
Here's the 11th version of the writeback patches. Changes since v10:
- I think this finally fixes the one show stopper issue I was aware
of. This is the one that Yanmin Zhang reported and which has plagued
this patch series for some time. Basically it was due to a race
between work queueing and exited tasks. I cleaned up this part while
fixing the bug.
- The three prep patches are now merged, so they have been deleted.
- Updated to current -git.
For ease of patching, I've put the full diff here:
http://kernel.dk/writeback-v11.patch
and also stored this in a writeback-v11 branch that will not change,
you can pull that into Linus tree from here:
git://git.kernel.dk/linux-2.6-block.git writeback-v11
Please test and report results/interesting finds. Thanks! I hope to merge
this work sooner rather than later, so please do give it a good beating.
