From: Christoph Hellwig Date: Mon, 18 Aug 2025 04:58:21 +0000 (+0200) Subject: dm error: mark as DM_TARGET_PASSES_INTEGRITY X-Git-Tag: v6.18-rc1~101^2~19 X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=499cbe0f2fb0641cf07a1a8ac9f7317674295fea;p=thirdparty%2Flinux.git dm error: mark as DM_TARGET_PASSES_INTEGRITY 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.
