Ahh, you're correct. I've been doing a lot of NFS work lately and was
thinking stateless... :-)

That patch should be OK then, though I think if someone is purposefully
setting the atime we should take care not to clobber it. We're not
going to be going through this codepath on every atime update, are we?
Just on utimes() type calls, correct? If so, doing a flush on atime
updates might be reasonable as well...
