    cfq: change the meaning of the cfqq_coop flag · b3b6d040
    Jeff Moyer authored
    The flag used to indicate that a cfqq was allowed to jump ahead in the
    scheduling order due to submitting a request close to the queue that
    just executed.  Since closely cooperating queues are now merged, the flag
    holds little meaning.  Change it to indicate that multiple queues were
    merged.  This will later be used to allow the breaking up of merged queues
    when they are no longer cooperating.
