Pull more block updates from Jens Axboe:
"A combination of changes that ended up depending on both the driver
and core branch (and/or the IDE removal), and a few late arriving
fixes. In detail:
- Fix io ticks wrap-around issue (Chunguang)
- nvme-tcp sock locking fix (Maurizio)
- s390-dasd fixes (Kees, Christoph)
- blk_execute_rq polling support (Keith)
- blk-cgroup RCU iteration fix (Yu)
- nbd backend ID addition (Prasanna)
- Partition deletion fix (Yufen)
- Use blk_mq_alloc_disk for mmc, mtip32xx, ubd (Christoph)
- Removal of now dead block request types due to IDE removal
(Christoph)
- Loop probing and control device cleanups (Christoph)
- Device uevent fix (Christoph)
- Misc cleanups/fixes (Tetsuo, Christoph)"
