Subject[PATCH 5.19 135/158] Revert "md-raid: destroy the bitmap after destroying the thread"
Date
From: Guoqing Jiang <guoqing.jiang@linux.dev>

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.

Fixes: e151db8ecfb0 ("md-raid: destroy the bitmap after destroying the thread")
