I do not think noatime will have any affect on the filesystem unless
you get it in there on the initial mount - difficult on the root I know.
As for the logbufs thing, the string of what is in the mount options
reported by the kernel has nothing to do with xfs itself, it is all
done with smoke and mirrors in the vfs layer.
