[Greg Kroah-Hartman]

4.14-stable review patch.  If anyone has any objections, please let me know.

From: Keith Busch <keith.busch@xxxxxxxxx>

[ Upstream commit f31a21103c03bb62846409fdc60cc9faf2398cfb ]

If the command a separate metadata buffer attached, the request needs
to have the integrity flag set so the driver knows to map it.
