Subject: [PATCH 70/79] xfs: switch to new ctime accessors
Date:   Wed, 21 Jun 2023 10:46:23 -0400
Message-ID: <20230621144735.55953-69-jlayton@kernel.org>
In-Reply-To: <20230621144735.55953-1-jlayton@kernel.org>
References: <20230621144507.55591-1-jlayton@kernel.org>
 <20230621144735.55953-1-jlayton@kernel.org>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

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