Subject: [PATCH 05/10] gfs2: honor AT_STATX_DONT_SYNC
Date: Wed, 20 Sep 2017 10:40:00 +0200 [thread overview]
Message-ID: <1505896805-12055-6-git-send-email-mszeredi@redhat.com> (raw)
In-Reply-To: <1505896805-12055-1-git-send-email-mszeredi@redhat.com>
The description of this flag says "Don't sync attributes with the server".
In other words: always use the attributes cached in the kernel and don't
send network or local messages to refresh the attributes.
