Re: [PATCH] Time sliced cfq with basic io priorities

[Jens Axboe]

Hi,

Version -12 has been uploaded. Changes:

- Small optimization to choose next request logic

- An idle queue that exited would waste time for the next process

- Request allocation changes. Should get a smooth stream for writes now,
  not as bursty as before. Also simplified the may_queue/check_waiters
  logic, rely more on the regular block rq allocation congestion and
  don't waste sys time doing multiple wakeups.

- Fix compilation on x86_64

No io priority specific fixes, the above are all to improve the cfq time
slicing.

For 2.6.10-rc3-mm1:
