Merge tag 'for-linus-20190420' of git://git.kernel.dk/linux-block
Pull block fixes from Jens Axboe:
"A set of small fixes that should go into this series. This contains:
- Removal of unused queue member (Hou)
- Overflow bvec fix (Ming)
- Various little io_uring tweaks (me)
- kthread parking
- Only call cpu_possible() for verified CPU
- Drop unused 'file' argument to io_file_put()
- io_uring_enter vs io_uring_register deadlock fix
- CQ overflow fix
- BFQ internal depth update fix (me)"
