v2:
amend description:
for RB tree traveler we don't need to travel to
the bottom level if already found the equal size node,
thus the search performance can get improved.

v3:
split "<=" to "<" case and "==" case

Tested-by: Rex Zhu <Rex.zhu@xxxxxxx>
Signed-off-by: Monk Liu <Monk.Liu@xxxxxxx>
Still fundamentally broken.

Can you explain that further? Do we need to return the deepest hole of the right size because the following algorithm depends on that?

Thanks,
Christian.
