From: Keith Busch <kbusch at kernel.org>

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
