From mboxrd@z Thu Jan 1 00:00:00 1970 From: Tiger Yang Date: Wed, 2 Mar 2011 19:32:09 +0800 Subject: [Ocfs2-devel] [PATCH 1/1] ocfs2: clean up mount option about atime in ocfs2.txt In-Reply-To: <4D6E2994.1050302@oracle.com> References: <4D6E2994.1050302@oracle.com> Message-ID: <1299065529-6626-1-git-send-email-tiger.yang@oracle.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: ocfs2-devel@oss.oracle.com As ocfs2 supports relatime and strictatime, we need update the relative document. Atime_quantum need work with strictatime, so only show it in procfs when mount with strictatime.
