Hi all,

After merging the akpm-current tree, today's linux-next build (x86_64
allmodconfig) produced this warning:

lib/rbtree_test.c: In function 'check_augmented':
lib/rbtree_test.c:220:18: warning: unused variable 'rb' [-Wunused-variable]
  struct rb_node *rb;
                  ^~

Introduced by commit

  33a64f781816 ("augmented-rbtree-add-new-rb_declare_callbacks_max-macro-fix-2")
