Revision 630ef623ed26c18a457cdc070cf24014e50129c2 authored by Bart Van Assche on 13 May 2021, 17:15:29 UTC, committed by Jens Axboe on 14 May 2021, 14:59:31 UTC
If a tag set is shared across request queues (e.g. SCSI LUNs) then the
block layer core keeps track of the number of active request queues in
tags->active_queues. blk_mq_tag_busy() and blk_mq_tag_idle() update that
atomic counter if the hctx flag BLK_MQ_F_TAG_QUEUE_SHARED is set. Make
sure that blk_mq_exit_queue() calls blk_mq_tag_idle() before that flag is
cleared by blk_mq_del_queue_tag_set().
