The patch titled Subject: lib/generic-radix-tree.c: make 2 functions static inline has been removed from the -mm tree. Its filename was lib-generic-radix-treec-make-2-functions-static-inline.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Valdis Kletnieks <valdis.kletnieks@xxxxxx> Subject: lib/generic-radix-tree.c: make 2 functions static inline When building with W=1, we get some warnings: l CC lib/generic-radix-tree.o lib/generic-radix-tree.c:39:10: warning: no previous prototype for 'genradix_root_to_depth' [-Wmissing-prototypes] 39 | unsigned genradix_root_to_depth(struct genradix_root *r) | ^~~~~~~~~~~~~~~~~~~~~~ lib/generic-radix-tree.c:44:23: warning: no previous prototype for 'genradix_root_to_node' [-Wmissing-prototypes] 44 | struct genradix_node *genradix_root_to_node(struct genradix_root *r) | ^~~~~~~~~~~~~~~~~~~~~ They're not used anywhere else, so make them static inline.
