Subject: [PATCH v2 47/92] gfs2: convert to ctime accessor functions
Date:   Wed,  5 Jul 2023 15:01:12 -0400
Message-ID: <20230705190309.579783-45-jlayton@kernel.org>
In-Reply-To: <20230705190309.579783-1-jlayton@kernel.org>
References: <20230705185755.579053-1-jlayton@kernel.org>
 <20230705190309.579783-1-jlayton@kernel.org>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

In later patches, we're going to change how the inode's ctime field is
used. Switch to using accessor functions instead of raw accesses of
inode->i_ctime.
