Merge branch 'for-linus' of git://git.kernel.dk/linux-block
Pull block fixes from Jens Axboe: "A collection of fixes since the merge window; - fix for a double elevator module release, from Chao Yu. Ancient bug. - the splice() MORE flag fix from Christophe Leroy. - a fix for NVMe, fixing a patch that went in in the merge window. From Keith. - two fixes for blk-mq CPU hotplug handling, from Ming Lei. - bdi vs blockdev lifetime fix from Neil Brown, fixing and oops in md. - two blk-mq fixes from Shaohua, fixing a race on queue stop and a bad merge issue with FUA writes. - division-by-zero fix for writeback from Tejun. - a block bounce page accounting fix, making sure we inc/dec after bouncing so that pre/post IO pages match up. From Wang YanQing" * 'for-linus' of git://git.kernel.dk/linux-block: splice: sendfile() at once fails for big files blk-mq: don't lose requests if a stopped queue restarts blk-mq: fix FUA request hang block: destroy bdi before blockdev is unregistered. block:bounce: fix call inc_|dec_zone_page_state on different pages confuse value of NR_BOUNCE elevator: fix double release of elevator module writeback: use |1 instead of +1 to protect against div by zero blk-mq: fix CPU hotplug handling blk-mq: fix race between timeout and CPU hotplug NVMe: Fix VPD B0 max sectors translation
