To ease review please try to make the patch as minimal as possible, i.e.
the above could be done as:

-		struct hist_entry *he = rb_entry(next, struct hist_entry, rb_node);
+		struct hist_entry *he = rb_entry(next, struct hist_entry, rb_node_in);
 		struct hist_entry *pair = hist_entry__next_pair(he);

-		next = rb_next(&he->rb_node);
+		next = rb_next(&he->rb_node_in);

See how we can more quickly see what happened? I.e. just replacing
'rb_node' with 'rb_node_in' :-)
