lib/rbtree: enable userland test suite for rbtree related data structure
Patch series "lib/interval_tree: add some test cases and cleanup", v2. Since rbtree/augmented tree/interval tree share similar data structure, besides new cases for interval tree, this patch set also does cleanup for others. This patch (of 7): Currently we have some tests for rbtree related data structure, e.g. rbtree, augmented rbtree, interval tree, in lib/ as kernel module. To facilitate the test and debug for those fundamental data structure, this patch enable those tests in userland.
