John, any feedback on this?

Sorry, yea, I've been meaning to get back to this.

I'm still on the fence about just making getnstimeofday() safe for when timekeeping is suspended, but at the same time, your issue needs fixing. Also bailing out at the end still seems off to me. Even if someone is using the values despite the WARN_ON, they really are getting junk values, and for all the time that WARN_ON has been there, you're the first to report running into it.

Even so, I think I'm ok with this patch for now, but I suspect we may want to rework it later.

Looking at my inbox, I actually can't find a copy of this specific patch. Do you mind bouncing it to me, so I have something I can apply?

Should this also get marked for -stable?

thanks
-john
