+Subject: [PATCH] Revert "libblkid: try LUKS2 first when probing"
+
+mdadm superblocks before 1.1 are placed at the end of the device, which
+means that the data contained inside the array starts at offset 0. For
+LUKS inside MD, blkid falsely detects this as plain LUKS instead of a
+linux_raid_member. This causes e.g. dracut to not assemble the array
+during boot and system startup fails.
+
+This reverts commit b8889c0a214aeb3dd47bf1ab280fe5534b64d2aa.
