Subject: [PATCH v2 1/2] jbd2: correct the printing of write_flags in jbd2_write_superblock()
Date: Wed, 29 Nov 2023 19:47:39 +0800	[thread overview]
Message-ID: <20231129114740.2686201-1-yi.zhang@huaweicloud.com> (raw)

From: Zhang Yi <yi.zhang@huawei.com>

The write_flags print in the trace of jbd2_write_superblock() is not
real, so move the modification before the trace.
