OK. I've been using noatime systematically for years. And then I read about a prominent kernel developer like Molnar using both noatime and nodiratime, making me worried: Have I been missing out on I/O-performance for years?

- But your definite statement is comforting, thanks. I'll keep using just "noatime".

noatime is a superset of nodiratime, btw.
I trust Andrew on this point. :-)
