[PATCH -next v6 2/5] dm-raid: remove useless checking in raid_message()

From: Yu Kuai
Date: Thu Apr 13 2023 - 07:33:34 EST


From: Yu Kuai <yukuai3@xxxxxxxxxx>

md_wakeup_thread() handle the case that pass in md_thread is NULL, there
is no need to check this. Prepare to protect md_thread with rcu.
