From 761b3ef50e1c2649cffbfa67a4dcb2dcdb7982ed Mon Sep 17 00:00:00 2001 From: Li Zefan Date: Tue, 31 Jan 2012 13:47:36 +0800 Subject: cgroup: remove cgroup_subsys argument from callbacks The argument is not used at all, and it's not necessary, because a specific callback handler of course knows which subsys it belongs to. Now only ->pupulate() takes this argument, because the handlers of this callback always call cgroup_add_file()/cgroup_add_files(). So we reduce a few lines of code, though the shrinking of object size is minimal. 16 files changed, 113 insertions(+), 162 deletions(-) text data bss dec hex filename 5486240 656987 7039960 13183187 c928d3 vmlinux.o.orig 5486170 656987 7039960 13183117 c9288d vmlinux.o Signed-off-by: Li Zefan Signed-off-by: Tejun Heo --- net/sched/cls_cgroup.c | 10 ++++------ 1 file changed, 4 insertions(+), 6 deletions(-) (limited to 'net/sched') diff --git a/net/sched/cls_cgroup.c b/net/sched/cls_cgroup.c index f84fdc3a7f27..1afaa284fcd7 100644 --- a/net/sched/cls_cgroup.c +++ b/net/sched/cls_cgroup.c @@ -22,9 +22,8 @@ #include #include -static struct cgroup_subsys_state *cgrp_create(struct cgroup_subsys *ss, - struct cgroup *cgrp); -static void cgrp_destroy(struct cgroup_subsys *ss, struct cgroup *cgrp); +static struct cgroup_subsys_state *cgrp_create(struct cgroup *cgrp); +static void cgrp_destroy(struct cgroup *cgrp); static int cgrp_populate(struct cgroup_subsys *ss, struct cgroup *cgrp); struct cgroup_subsys net_cls_subsys = { @@ -51,8 +50,7 @@ static inline struct cgroup_cls_state *task_cls_state(struct task_struct *p) struct cgroup_cls_state, css); } -static struct cgroup_subsys_state *cgrp_create(struct cgroup_subsys *ss, - struct cgroup *cgrp) +static struct cgroup_subsys_state *cgrp_create(struct cgroup *cgrp) { struct cgroup_cls_state *cs; @@ -66,7 +64,7 @@ static struct cgroup_subsys_state *cgrp_create(struct cgroup_subsys *ss, return &cs->css; } -static void cgrp_destroy(struct cgroup_subsys *ss, struct cgroup *cgrp) +static void cgrp_destroy(struct cgroup *cgrp) { kfree(cgrp_cls_state(cgrp)); } -- cgit v1.2.1
