Patch "dm mpath: fix passing integrity data" has been added to the 4.15-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled dm mpath: fix passing integrity data to the 4.15-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: dm-mpath-fix-passing-integrity-data.patch and it can be found in the queue-4.15 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From 8c5c147339d2e201108169327b1f99aa6d57d2cd Mon Sep 17 00:00:00 2001 From: Steffen Maier <maier(a)linux.vnet.ibm.com> Date: Wed, 14 Mar 2018 15:33:06 +0100 Subject: dm mpath: fix passing integrity data From: Steffen Maier <maier(a)linux.vnet.ibm.com> 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.
