Handling passthrough metadata ("integrity") today introduces overhead
and complications that we can avoid if we just map user space addresses
directly. This patch series implements that.
Keith Busch (4):
block: bio-integrity: add support for user buffers
nvme: use bio_integrity_map_user
iouring: remove IORING_URING_CMD_POLLED
io_uring: remove uring_cmd cookie
