From 9cd43611ccfb46632bfa7d19f688924ea93f1613 Mon Sep 17 00:00:00 2001 From: Emese Revfy Date: Thu, 31 Dec 2009 14:52:51 +0100 Subject: kobject: Constify struct kset_uevent_ops Constify struct kset_uevent_ops. This is part of the ops structure constification effort started by Arjan van de Ven et al. Benefits of this constification: * prevents modification of data that is shared (referenced) by many other structure instances at runtime * detects/prevents accidental (but not intentional) modification attempts on archs that enforce read-only kernel data at runtime * potentially better optimized code as the compiler can assume that the const data cannot be changed * the compiler/linker move const data into .rodata and therefore exclude them from false sharing Signed-off-by: Emese Revfy Signed-off-by: Greg Kroah-Hartman --- lib/kobject.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'lib/kobject.c') diff --git a/lib/kobject.c b/lib/kobject.c index b512b74..cecf5a0 100644 --- a/lib/kobject.c +++ b/lib/kobject.c @@ -789,7 +789,7 @@ static struct kobj_type kset_ktype = { * If the kset was not able to be created, NULL will be returned. */ static struct kset *kset_create(const char *name, - struct kset_uevent_ops *uevent_ops, + const struct kset_uevent_ops *uevent_ops, struct kobject *parent_kobj) { struct kset *kset; @@ -832,7 +832,7 @@ static struct kset *kset_create(const char *name, * If the kset was not able to be created, NULL will be returned. */ struct kset *kset_create_and_add(const char *name, - struct kset_uevent_ops *uevent_ops, + const struct kset_uevent_ops *uevent_ops, struct kobject *parent_kobj) { struct kset *kset; -- cgit v1.1
