      [PATCH] blk: fix merge bug in as-iosched · 47e627ce
      Tejun Heo authored
      as-iosched deals with aliased requests differently from other ioscheds.
      It links together aliased requests using rq->queuelist instead of
      spilling alises to dispatch queue like other ioscheds do.  Requests
      linked in this way cannot be merged.
      Unfortunately, generic q->last_merge handling patch didn't take this
      into account and q->last_merge could be set to an aliased request
      resulting in Badness, corrupt list and eventually panic.
      This explicitly marks aliased requests to be unmergeable.
