stacking ontop of blk-mq devices. This blk-mq support changes the model request-based DM uses for cloning a request to relying on calling blk_get_request() directly from the underlying blk-mq device. Early consumer of this code is Intel's emerging NVMe hardware; thanks to Keith Busch for working on, and pushing for, these changes. - A few other small fixes and cleanups across other DM targets. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEcBAABAgAGBQJU3NRnAAoJEMUj8QotnQNavG0H/3yogMcHvKg9H+w0WmUQdwhN w99Wj3nkquAw2sm9yahKlAMBNY53iu/LHmC6/PaTpJetgdH7y1foTrRa0qjyeB2D DgNr8mOzxSxzX6CX9V8JMwqzky9XoG2IOt/7FeQQOpMqp4T1M2zgvbZtpl0lK/f3 lNaNBFpl+47NbGssD/WbtfI4Yy3hX0u406yGmQN5DxRyGTWD2AFqpA76g2mp8vrp wmw259gPr4oLhj3pDc0GkuiVn59ZR2Zp+2gs0jD5uKlDL84VP/nE+WNB+ny1Mnmt cOg8Q+W6/OosL66MKBHNsF0QS6DXNo5UvsN9fHGa5IUJw7Tsa11ZEPKHZGEbQw4= =RiN2 -----END PGP SIGNATURE----- Merge tag 'dm-3.20-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm Pull device mapper changes from Mike Snitzer: - The most significant change this cycle is request-based DM now supports stacking ontop of blk-mq devices.
