Subject: rbtree: include rcu.h
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=2075b16e32c26e4031b9fd3cbe26c54676a8fcb5;p=linux.git

rbtree: include rcu.h

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.
