Merge branch 'for-linus' of git://git.kernel.dk/linux-block
Pull more block layer updates from Jens Axboe: "A followup pull request, with some parts that either needed a bit more testing before going in, merge sync, or just later arriving fixes. This contains: - Timer related updates from Kees. These were purposefully delayed since I didn't want to pull in a later v4.14-rc tag to my block tree. - ide-cd prep sense buffer fix from Bart. Also delayed, as not to clash with the late fix we put into 4.14-rc. - Small BFQ updates series from Luca and Paolo. - Single nvmet fix from James, fixing a non-functional case there. - Bio fast clone fix from Michael, which made bcache return the wrong data for some cases. - Legacy IO path regression hang fix from Ming" * 'for-linus' of git://git.kernel.dk/linux-block: bio: ensure __bio_clone_fast copies bi_partno nvmet_fc: fix better length checking block: wake up all tasks blocked in get_request() block, bfq: move debug blkio stats behind CONFIG_DEBUG_BLK_CGROUP block, bfq: update blkio stats outside the scheduler lock block, bfq: add missing invocations of bfqg_stats_update_io_add/remove doc, block, bfq: update max IOPS sustainable with BFQ ide: Make ide_cdrom_prep_fs() initialize the sense buffer pointer md: Convert timers to use timer_setup() block: swim3: Convert timers to use timer_setup() block/aoe: Convert timers to use timer_setup() amifloppy: Convert timers to use timer_setup() block/floppy: Convert callback to pass timer_list
