> Yeah, there always is. The open coded rb_tree searches can be converted to the rb_find() helpers. It ends up as the same asm code due to inlining and reads a bit better when there's just one rb_find instead of the while loop and left/right tree moves.

OK, thank you very much for the detailed idea!

I will spend time on this.
