Re: [take10 1/2] kevent: Core files.

+void kevent_user_ring_add_event(struct kevent *k)
+{
+	unsigned int pidx, off;
+	struct kevent_mring *ring, *copy_ring;
+
+	ring = (struct kevent_mring *)k->user->pring[0];
+	
+	pidx = ring->index/KEVENTS_ON_PAGE;
+	off = ring->index%KEVENTS_ON_PAGE;
+
+	copy_ring = (struct kevent_mring *)k->user->pring[pidx];
+
+	copy_ring->event[off].id.raw[0] = k->event.id.raw[0];
+	copy_ring->event[off].id.raw[1] = k->event.id.raw[1];
+	copy_ring->event[off].ret_flags = k->event.ret_flags;
+
+	if (++ring->index >= KEVENT_MAX_EVENTS)
+		ring->index = 0;
+}

Can you assume that the page at pidx is already allocated and why?
