[PATCH 0/2] blk-mq-dma: p2p cleanups and integrity fixup

[Keith Busch]

From: Keith Busch <kbusch at kernel.org>

After reviewing and discussing with Leon and Jason on some of the
proposed updates, it became clean that having the callers track p2p dma
usage doesn't scale, and we have a convenient way to track these things
in the existing structures anyway. So, thank goodness nvme is the only
client of this API at the moment while we work out the kinks.

While looking at it, I also noticed that integrity wouldn't attempt to
use p2p pages, which I think was simply an oversight.

Keith Busch (2):
  blk-integrity: enable p2p source and destination
  blk-mq-dma: bring back p2p request flags
