tools lib rbtree: Pick some improvements from the kernel rbtree code
The tools/lib/rbtree.c code came from the kernel, removing the EXPORT_SYMBOL() that make sense only there, unfortunately it is not being checked with tools/perf/check_headers.sh, will try to remedy this, till then pick the improvements from: b0687c1119b4e8c8 ("lib/rbtree: use '+' instead of '|' for setting color.") That I noticed by doing: diff -u tools/lib/rbtree.c lib/rbtree.c diff -u tools/include/linux/rbtree_augmented.h include/linux/rbtree_augmented.h There is one other cases, but lets pick it in separate patches.
