Originally reported by Tetsuo and Fernando at last year, Mar 2013. This v4 updates v3's approach, and adds description/comments to make patch's intent to be clear (I hope so). Of course still reviews are welcome. Thanks, H.Seto Hidetoshi Seto (2): nohz: make updating sleep stats local nohz: delayed iowait accounting for nohz idle time stats include/linux/tick.h | 6 +- kernel/time/tick-sched.c | 179 ++++++++++++++++++++++++++++++++++------------ 2 files changed, 136 insertions(+), 49 deletions(-)
