[PATCHv5 0/4] block integrity: directly map user space addresses

[Keith Busch <kbusch@meta.com>]

From: Keith Busch <kbusch@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, falling back to a kernel
bounce buffer if necessary.

v4->v5:

  Unpin user pages after setup for write commands (Kanchan)

  Added reviews to the unchanged patches (Christoph, Martin)

Keith Busch (4):
  block: bio-integrity: directly map user buffers
  nvme: use bio_integrity_map_user
  iouring: remove IORING_URING_CMD_POLLED
  io_uring: remove uring_cmd cookie
