From 0199849acd07d07e2a8e42757653ca8b14a122f5 Mon Sep 17 00:00:00 2001 From: Luis Chamberlain Date: Tue, 2 May 2023 18:30:04 -0700 Subject: sysctl: remove register_sysctl_paths() The deprecation for register_sysctl_paths() is over. We can rejoice as we nuke register_sysctl_paths(). The routine register_sysctl_table() was the only user left of register_sysctl_paths(), so we can now just open code and move the implementation over to what used to be to __register_sysctl_paths(). The old dynamic struct ctl_table_set *set is now the point to sysctl_table_root.default_set. The old dynamic const struct ctl_path *path was being used in the routine register_sysctl_paths() with a static: static const struct ctl_path null_path[] = { {} }; Since this is a null path we can now just simplfy the old routine and remove its use as its always empty. This saves us a total of 230 bytes. $ ./scripts/bloat-o-meter vmlinux.old vmlinux add/remove: 2/7 grow/shrink: 1/1 up/down: 1015/-1245 (-230) Function old new delta register_leaf_sysctl_tables.constprop - 524 +524 register_sysctl_table 22 497 +475 __pfx_register_leaf_sysctl_tables.constprop - 16 +16 null_path 8 - -8 __pfx_register_sysctl_paths 16 - -16 __pfx_register_leaf_sysctl_tables 16 - -16 __pfx___register_sysctl_paths 16 - -16 __register_sysctl_base 29 12 -17 register_sysctl_paths 18 - -18 register_leaf_sysctl_tables 534 - -534 __register_sysctl_paths 620 - -620 Total: Before=21259666, After=21259436, chg -0.00% Signed-off-by: Luis Chamberlain --- include/linux/sysctl.h | 12 ------------ 1 file changed, 12 deletions(-) (limited to 'include/linux') diff --git a/include/linux/sysctl.h b/include/linux/sysctl.h index 780690dc08cd..3d08277959af 100644 --- a/include/linux/sysctl.h +++ b/include/linux/sysctl.h @@ -221,14 +221,8 @@ extern void retire_sysctl_set(struct ctl_table_set *set); struct ctl_table_header *__register_sysctl_table( struct ctl_table_set *set, const char *path, struct ctl_table *table); -struct ctl_table_header *__register_sysctl_paths( - struct ctl_table_set *set, - const struct ctl_path *path, struct ctl_table *table); struct ctl_table_header *register_sysctl(const char *path, struct ctl_table *table); struct ctl_table_header *register_sysctl_table(struct ctl_table * table); -struct ctl_table_header *register_sysctl_paths(const struct ctl_path *path, - struct ctl_table *table); - void unregister_sysctl_table(struct ctl_table_header * table); extern int sysctl_init_bases(void); @@ -277,12 +271,6 @@ static inline struct ctl_table_header *register_sysctl_mount_point(const char *p return NULL; } -static inline struct ctl_table_header *register_sysctl_paths( - const struct ctl_path *path, struct ctl_table *table) -{ - return NULL; -} - static inline struct ctl_table_header *register_sysctl(const char *path, struct ctl_table *table) { return NULL; -- cgit v1.2.3
