Subject: [PATCH v2 3/8] autofs: set ctime as well when mtime changes on a dir
Date:   Mon, 12 Jun 2023 06:45:19 -0400
Message-Id: <20230612104524.17058-4-jlayton@kernel.org>
In-Reply-To: <20230612104524.17058-1-jlayton@kernel.org>
References: <20230612104524.17058-1-jlayton@kernel.org>

Content-Transfer-Encoding: 8bit
Precedence: bulk

When adding entries to a directory, POSIX generally requires that the
ctime also be updated alongside the mtime.
