Subject[PATCH 0/11] Per-bdi writeback flusher threads v8
Date
Hi,

Here's the 8th version of the writeback patches. Changes since v7:

- Fold the "include default_backing_dev_info in writeback" patch into
the core, we should just do it from the beginning.
- More series cleanup, I think it should be mostly complete now. No
hunks are split between patches now (things like comments for
functions added earlier, and so on).
- Fix hang with calling bdi_wait_on_work_clear() inside the bdi_lock
mutex when the default wb thread had exited.
- Fix hang with queuing work on exited wb thread, it would have no
receipients since the default wb thread wrongly cleared the bit
from the register mask on exit. It must be persistent, which is
why it gets initialized on bdi_register() already.

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

http://kernel.dk/writeback-v8.patch

and also stored this in a writeback-v7 branch that will not change,
you can pull that into Linus tree from here:
