From da5ef6bb96158b0fc0d808704237a453af449124 Mon Sep 17 00:00:00 2001 From: Lai Jiangshan Date: Fri, 25 Jul 2008 01:47:25 -0700 Subject: [PATCH] cpuset: two minor code-cleanups In cpuset_update_task_memory_state() local variable struct task_struct *tsk = current; And local variable tsk is used 14 times and statement task_cs(tsk) is used twice in this function. So using task_cs(tsk) instead of task_cs(current) is better for readability. And "(struct cgroup_scanner *)&scan" is not good for readability also. (and "container_of" is used in cpuset_do_move_task(), not "(cpuset_hotplug_scanner *)scan") Signed-off-by: Lai Jiangshan Acked-by: Paul Menage Cc: Paul Jackson Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- kernel/cpuset.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/kernel/cpuset.c b/kernel/cpuset.c index ebbc9b082e48..91cf85b36dd5 100644 --- a/kernel/cpuset.c +++ b/kernel/cpuset.c @@ -365,7 +365,7 @@ void cpuset_update_task_memory_state(void) my_cpusets_mem_gen = top_cpuset.mems_generation; } else { rcu_read_lock(); - my_cpusets_mem_gen = task_cs(current)->mems_generation; + my_cpusets_mem_gen = task_cs(tsk)->mems_generation; rcu_read_unlock(); } @@ -1777,7 +1777,7 @@ static void move_member_tasks_to_cpuset(struct cpuset *from, struct cpuset *to) scan.scan.heap = NULL; scan.to = to->css.cgroup; - if (cgroup_scan_tasks((struct cgroup_scanner *)&scan)) + if (cgroup_scan_tasks(&scan.scan)) printk(KERN_ERR "move_member_tasks_to_cpuset: " "cgroup_scan_tasks failed\n"); } -- 2.20.1
