Subject: [PATCH -next 5/6] md: wake up 'resync_wait' at last in md_reap_sync_thread()
Date:   Wed, 22 Mar 2023 14:41:21 +0800

From: Yu Kuai <yukuai3@huawei.com>

We just replace md_reap_sync_thread() with wait_event(resync_wait, ...)
from action_store(), this patch just make sure action_store() will still
wait for everything to be done in md_reap_sync_thread().
