sched/cpuacct: Initialize root cpuacct earlier

2013-04-10T11:54:20Z

Now we don't need cpuacct_init(), and instead we just initialize root_cpuacct when it's defined. Signed-off-by: Li Zefan Cc: Tejun Heo Acked-by: Peter Zijlstra Link: http://lkml.kernel.org/r/51553834.9090701@huawei.com Signed-off-by: Ingo Molnar

sched/cpuacct: Clean up cpuacct.h

2013-04-10T11:54:19Z

Now most of the code in cpuacct.h can be moved to cpuacct.c Signed-off-by: Li Zefan Acked-by: Peter Zijlstra Link: http://lkml.kernel.org/r/515536D5.2080401@huawei.com Signed-off-by: Ingo Molnar

sched/cpuacct: Remove redundant NULL checks in cpuacct_acount_field()

2013-04-10T11:54:18Z

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.

sched/cpuacct: Remove redundant NULL checks in cpuacct_charge()

2013-04-10T11:54:18Z

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.

sched/cpuacct: Add cpuacct_acount_field()

2013-04-10T11:54:17Z

So we can remove open-coded cpuacct code in cputime.c. Signed-off-by: Li Zefan Acked-by: Peter Zijlstra Link: http://lkml.kernel.org/r/51553692.9060008@huawei.com Signed-off-by: Ingo Molnar

sched/cpuacct: Add cpuacct_init()

2013-04-10T11:54:16Z

So we don't open-coded initialization of cpuacct in core.c. Signed-off-by: Li Zefan Acked-by: Peter Zijlstra Link: http://lkml.kernel.org/r/51553687.1060906@huawei.com Signed-off-by: Ingo Molnar

sched: Split cpuacct code out of sched.h

2013-04-10T11:54:16Z

Add cpuacct.h and let sched.h include it. Signed-off-by: Li Zefan Acked-by: Peter Zijlstra Link: http://lkml.kernel.org/r/5155367B.2060506@huawei.com Signed-off-by: Ingo Molnar
