ctime: Provide noatime option
Most of the applications are {c|m}time dependant and very few are atime dependant. So provide noatime option to not update atime when ctime feature is enabled. Also this option has to be enabled with ctime feature to avoid unnecessary self heal. Since AFR/EC reads data from single subvolume, atime is only updated in one subvolume triggering self heal. updates: bz#1593538 Change-Id: I085fb33c882296545345f5df194cde7b6cbc337e Signed-off-by: Kotresh HR <khiremat@redhat.com>
