--------------------------------
commit 1d258758cf06a0734482989911d184dd5837ed4e upstream.
This reverts commit e151db8ecfb019b7da31d076130a794574c89f6f. Because it obviously breaks clustered raid as noticed by Neil though it fixed KASAN issue for dm-raid, let's revert it and fix KASAN issue in next commit.
