Seems to work for me, thanks!

Yeah, it seems that is currently unused (unimplemented). I assume the
idea was to put OOM notifications (or maybe unshare notifications) in
that ring.

Once I hear back on the first patch, I will resend as a series (the
event mechanism for paging requires the first patch for correctness).
