[ Upstream commit 499cbe0f2fb0641cf07a1a8ac9f7317674295fea ]
Mark dm error as DM_TARGET_PASSES_INTEGRITY so that it can be stacked on top of PI capable devices. The claim is strictly speaking as lie as dm error fails all I/O and doesn't pass anything on, but doing the same for integrity I/O work just fine :)
This helps to make about two dozen xfstests test cases pass on PI capable devices.
