--- Comment #11 from Miklos Szeredi <mszeredi at redhat.com> ---
The underlying problem is that auto invalidate cannot differentiate local and
remote modification based on mtime alone.

What NFS apprently does is refresh attributes immediately after a write (not
sure how often it does this, I guess not after each individual write).

FUSE maybe should do this if auto invalidation is enabled, but if the
filesystem can do its own invalidation, possibly based on better information
than c/mtime, then that seem to be a better option.
