Hi,

Here's the 7th version of the writeback patches. Changes since
v5/v6:

- Move the sync_supers() to the global bdi_forker_task() thread, so we
  don't writeback the supers from all the bdi kupdated() tasks.
- Make bdi_start_writeback() and bdi_writeback_all() be sync when called
  with WB_SYNC_ALL only.
- Shuffle some more things around to make a cleaner series. The sync vs
  async nature of bdi_writeback_all() and bdi_start_writeback() isn't
  consistent through the series, but otherwise things should be sane.

I'd appreciate if Richard and Yanmin could re-run testing with this,
just to make sure that things are sane. For ease of patching, I've
put the full diff here:

  http://kernel.dk/writeback-v7.patch

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

  git://git.kernel.dk/linux-2.6-block.git writeback-v7
