    [BLOCK] as-iosched: update alias handling · ef9be1d3
    Tejun Heo authored
    Unlike other ioscheds, as-iosched handles alias by chaing them using
    rq->queuelist.  As aliased requests are very rare in the first place,
    this complicates merge/dispatch handling without meaningful
    performance improvement.  This patch updates as-iosched to dump
    aliased requests into dispatch queue as other ioscheds do.
