[PATCH v2 07/10] block, bfq: remove redundant check in bfq_put_cooperator

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



We have already avoided a circular list in bfq_setup_merge (see comments
in bfq_setup_merge() for details), so bfq_queue will not appear in it's
new_bfqq list. Just remove this check.
