Hi Jens, The 1st one fixes one regression caused by 20e4d81393 ("blk-mq: simplify queue mapping & schedule with each possisble CPU"). The 2nd one add commens about current race, and convert the WARN_ON into printk(KERN_WARN) since this warning is harmless. Thanks, Ming Lei (2): blk-mq: make sure hctx->next_cpu is set correctly blk-mq: convert WARN_ON in __blk_mq_run_hw_queue to printk block/blk-mq.c | 51 +++++++++++++++++++++++++++++++++++++++++++++++---- 1 file changed, 47 insertions(+), 4 deletions(-) -- 2.9.5
