• 22f17952c   blk-rq-qos: make depth comparisons unsigned ... Browse Code »

  With the change to use UINT_MAX I broke the depth check as any value of
  inflight (ie 0) would be less than (int)UINT_MAX. Fix this by changing
  everything to unsigned int to match the depth.

• 67b42d0bf   rq-qos: introduce dio_bio callback ... Browse Code »

  wbt cares only about request completion time, but controllers may need
  information that is on the bio itself, so add a done_bio callback for
  rq-qos so things like blk-iolatency can use it to have the bio when it
  completes.

• c1c80384c   block: remove external dependency on wbt_flags ... Browse Code »

  We don't really need to save this stuff in the core block code, we can
  just pass the bio back into the helpers later on to derive the same
  flags and update the rq->wbt_flags appropriately.

• a79050434   blk-rq-qos: refactor out common elements of blk-wbt ... Browse Code »

  blkcg-qos is going to do essentially what wbt does, only on a cgroup
  basis. Break out the common code that will be shared between blkcg-qos
  and wbt into blk-rq-qos.* so they can both utilize the same
  infrastructure.
