Subject: [PATCH v2 8/9] jbd2: remove dead check of JBD2_UNMOUNT in kjournald2
Date: Tue, 14 May 2024 19:24:37 +0800 [thread overview]
Message-ID: <20240514112438.1269037-9-shikemeng@huaweicloud.com> (raw)
In-Reply-To: <20240514112438.1269037-1-shikemeng@huaweicloud.com>
We always set JBD2_UNMOUNT with j_state_lock held in journal_kill_thread.
In kjournald2, we check JBD2_UNMOUNT flag two times under the same
j_state_lock. Then the second check is unnecessary.
