commit d05aa90384082c348113021500ac15716d060ead
Author: Christian Ambach <christian.ambach at de.ibm.com>
Date: Fri Feb 18 13:03:52 2011 +0100
s3:vfs:syncops add option to disable metasync per share
introduce an option to disable the metadata sync
in case the filesystem handles this correctly the sync can be
skipped, but synchronization of the data that was written can still
be configured (in opposition to the disable flag disabling all
sync operations)
