Subject: [PATCH 6/11] hfsplus: avoid useless work in hfsplus_sync_fs
Date: Wed, 17 Nov 2010 23:22:34 +0100 [thread overview]
Message-ID: <20101117222234.GG21700@lst.de> (raw)
In-Reply-To: <20101117222117.GA21700@lst.de>
There is no reason to write out the metadata inodes or volume headers
during a non-blocking sync, as we are almost guaranteed to dirty them
again during the inode writeouts.
