Subject: [PATCH v2 10/92] ubifs: convert to simple_rename_timestamp
Date:   Wed,  5 Jul 2023 15:00:35 -0400
Message-ID: <20230705190309.579783-8-jlayton@kernel.org>
In-Reply-To: <20230705190309.579783-1-jlayton@kernel.org>
References: <20230705185755.579053-1-jlayton@kernel.org>

A rename potentially involves updating 4 different inode timestamps.
Convert to the new simple_rename_timestamp helper function.
