    [PATCH] cfq-iosched.c: minor fixes · 9c2c38a1
    Jens Axboe authored
    One critical fix and two minor fixes for 2.6.13-rc7:
    - Max depth must currently be 2 to allow barriers to function on SCSI
    - Prefer sync request over async in choosing the next request
    - Never allow async request to preempt or disturb the "anticipation" for
      a single cfq process context. This is as-designed, the code right now
      is buggy in that area.
