The xarray.c file contains the only call to radix_tree_node_rcu_free(), and it comes with its own extern declaration for it. This means the function definition causes a missing-prototype warning: lib/radix-tree.c:288:6: error: no previous prototype for 'radix_tree_node_rcu_free' [-Werror=missing-prototypes] Instead, move the declaration for this function to a new header that can be included by both, and do the same for the radix_tree_node_cachep variable that has the same underlying problem but does not cause a warning with gcc.
