In Case 3 of `sibling == parent->rb_right': Right rotation will not change color of sl and S in the diagram (i.e. should not change "sl" to "Sl", "S" to "s") In Case 3 of `sibling == parent->rb_left': (p) (p) / \ / \ S N --> sr N / \ / Sl sr S / Sl This is actually left rotation at "S", not right rotation. In Case 4 of `sibling == parent->rb_left': (p) (s) / \ / \ S N --> Sl P / \ / \ sl (sr) (sr) N This is actually right rotation at "(p)" + color flips, not left rotation + color flips.
