rbtree: include rcu.h
foobar@foobar.de
Foo Bar
Fri May 11 16:02:14 2018 -0700
Since commit c1adf20052d8 ("Introduce rb_replace_node_rcu()")
rbtree_augmented.h uses RCU related data structures but does not include
the header file.  It works as long as it gets somehow included before
that and fails otherwise.
