2013-04-10	sched/cpuacct: Initialize root cpuacct earlier	Li Zefan	1	-5/+0
	Now we don't need cpuacct_init(), and instead we just initialize root_cpuacct when it's defined.

2013-04-10	sched/cpuacct: Clean up cpuacct.h	Li Zefan	1	-46/+0
	Now most of the code in cpuacct.h can be moved to cpuacct.c Signed-off-by: Li Zefan <lizefan@huawei.com> Acked-by: Peter Zijlstra <peterz@infradead.org> Link: http://lkml.kernel.org/r/515536D5.2080401@huawei.com Signed-off-by: Ingo Molnar <mingo@kernel.org>
2013-04-10	sched/cpuacct: Remove redundant NULL checks in cpuacct_acount_field()	Li Zefan	1	-0/+5
	This is a micro optimazation for a hot path. - We don't need to check if @ca returned from task_ca() is NULL. - We don't need to check if @ca returned from parent_ca() is NULL.

2013-04-10	sched/cpuacct: Remove redundant NULL checks in cpuacct_charge()	Li Zefan	1	-1/+1
	This is a micro optimization for the hot path. - We don't need to check if @ca is NULL in parent_ca(). - We don't need to check if @ca is NULL in the beginning of the for loop.

2013-04-10	sched/cpuacct: Add cpuacct_acount_field()	Li Zefan	1	-0/+6
	So we can remove open-coded cpuacct code in cputime.c. Signed-off-by: Li Zefan <lizefan@huawei.com> Acked-by: Peter Zijlstra <peterz@infradead.org> Link: http://lkml.kernel.org/r/51553692.9060008@huawei.com Signed-off-by: Ingo Molnar <mingo@kernel.org>
2013-04-10	sched/cpuacct: Add cpuacct_init()	Li Zefan	1	-0/+5
	So we don't open-coded initialization of cpuacct in core.c. Signed-off-by: Li Zefan <lizefan@huawei.com> Acked-by: Peter Zijlstra <peterz@infradead.org> Link: http://lkml.kernel.org/r/51553687.1060906@huawei.com Signed-off-by: Ingo Molnar <mingo@kernel.org>
2013-04-10	sched: Split cpuacct code out of sched.h	Li Zefan	1	-0/+52
	Add cpuacct.h and let sched.h include it. Signed-off-by: Li Zefan <lizefan@huawei.com> Acked-by: Peter Zijlstra <peterz@infradead.org> Link: http://lkml.kernel.org/r/5155367B.2060506@huawei.com Signed-off-by: Ingo Molnar <mingo@kernel.org>
