+Subject: [PATCH 91/95] dm raid: fix flush support
+
+commit 0ca93de9b789e0eb05e103f0c04de72df13da73a upstream.
+
+Fix dm-raid flush support.
+
+Both md and dm have support for flush, but the dm-raid target
+forgot to set the flag to indicate that flushes should be
+passed on.  (Important for data integrity e.g. with writeback cache
+enabled.)
