btw., "relatime" does not seem to make much of a difference, if i do 
this:

  ls -l x ; sync

on a "relatime" mounted filesystem ('x' is a regular file), then there's 
disk IO for every such command. Only if i mount it noatime,nodiratime do 
i get zero disk IO. Or my patch is wrong somehow.

do we have reldiratime ?
