This patchset cleans up on kojects of request_queue.mq_kobj, sw queue's kobject and hw queue's kobject.
The 1st patch initialized kobject of request_queue and sw queue in blk_mq_init_allocated_queue(), so we can avoid to initialize these kobjects several times, and this patch fixes one kerne warning reported from Omar Sandoval. The 2nd patch makes lifetime consitent between mq request queue/sw queue and their kobjects. The 3rd patch makes lifetime consitent between hw queue and their kobjects. The last patch is a followup of 3rd patch. Thanks, Ming Ming Lei (4): blk-mq: initialize mq kobjects in blk_mq_init_allocated_queue() blk-mq: make lifetime consitent between q/ctx and its kobject blk-mq: make lifetime consistent between hctx and its kobject blk-mq: free hctx->cpumask in release handler of hctx's kobject block/blk-mq-sysfs.c | 40 +++++++++++++++++++++++++--------------- block/blk-mq.c | 28 ++++++++++------------------ block/blk-mq.h | 2 ++ 3 files changed, 37 insertions(+), 33 deletions(-) -- 2.7.4
