Hi Jens, In commit a1ce35fa49852db60fc6e268038530be533c5b15 ("block: remove dead elevator code") you removed all users of RQF_SORTED. However there is still one reference left to it: block/blk-mq-sched.c:412: rq->rq_flags |= RQF_SORTED; This in effect is dead code now. Should this statement have been removed as part of the aforementioned commit? And then maybe also the definition of RQF_SORTED, to prevent further confusion? Thanks, -- Jean Delvare SUSE L3 Support
