4.14-stable review patch. If anyone has any objections, please let me know. ------------------ From: Steffen Maier <maier@xxxxxxxxxxxxxxxxxx> commit 8c5c147339d2e201108169327b1f99aa6d57d2cd upstream. After v4.12 commit e2460f2a4bc7 ("dm: mark targets that pass integrity data"), dm-multipath, e.g. on DIF+DIX SCSI disk paths, does not support block integrity any more. So add it to the whitelist. This is also a pre-requisite to use block integrity with other dm layer(s) on top of multipath, such as kpartx partitions (dm-linear) or LVM. Also, bump target version to reflect this fix.
