I also suggest that "extern bool nopv" might be a bit non-specific and could use a longer identifier. You are a little bit late. It has been this way since V5 of the series posted on July 3rd. I have pushed the series to my tree already and I'm about to send the pull request. Followup patches welcome. :-) Juergen ___ Xen-devel mailing list Xen-devel@lists.xenproject.org https://lists.xenproject.org/mailman/listinfo/xen-devel
