We get 4 warnings when building kernel with W=1: drivers/vhost/vhost.c:52:23: warning: no previous prototype for 'vhost_umem_interval_tree_insert' [-Wmissing-prototypes] drivers/vhost/vhost.c:52:23: warning: no previous prototype for 'vhost_umem_interval_tree_remove' [-Wmissing-prototypes] drivers/vhost/vhost.c:52:23: warning: no previous prototype for 'vhost_umem_interval_tree_iter_first' [-Wmissing-prototypes] drivers/vhost/vhost.c:52:23: warning: no previous prototype for 'vhost_umem_interval_tree_iter_next' [-Wmissing-prototypes] In fact, these functions are defined in the macro 'INTERVAL_TREE_DEFINE' in include/linux/interval_tree_generic.h and don't need a declaration, but can be made static. so this patch marks these functions with 'static' by modifying the macro.
