From 1a5fab846c9b97358a547031d27eabc1e257bd52 Mon Sep 17 00:00:00 2001 From: Jonathan E Brassow Date: Wed, 7 Mar 2012 19:09:48 +0000 Subject: [PATCH] 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.)
