| |
To fix:
In file included from include/linux/interval_tree_generic.h:22:0, from lib/interval_tree.c:2: include/linux/rbtree_augmented.h: In function ‘__rb_change_child_rcu’: include/linux/rbtree_augmented.h:139:4: error: implicit declaration of function ‘rcu_assign_pointer’ [-Werror=implicit-function-declaration] rcu_assign_pointer(parent->rb_left, new);
...which shows up on some -rt builds once the rb_replace_node_rcu was added. Since rcu_assign_pointer is clearly used, just add the header for it to the file in question.
