The 2nd one add comments for current two races, and convert the WARN_ON into printk(KERN_WARN) with dump_stack() since this warning is harmless. V2: - fix comment and commit log in patch 1 - use dump_stack() with printk to replace WARN_ON() in patch 2 Thanks, Ming Lei (2): blk-mq: make sure hctx->next_cpu is set correctly blk-mq: avoid one WARN_ON in __blk_mq_run_hw_queue to printk block/blk-mq.c | 52 ++++++++++++++++++++++++++++++++++++++++++++++++---- 1 file changed, 48 insertions(+), 4 deletions(-) -- 2.9.5
