| |
Hi all,
This patch set (rebased on v3.14-rc8) will fix an issue that idle/iowait of /proc/stat can go backward. Originally reported by Tetsuo and Fernando at last year, Mar 2013.
v2 have Preeti's Reviewed-by (Thanks!). Of course still reviews are welcome.
Thanks, H.Seto
Hidetoshi Seto (2): nohz: use seqlock to avoid race on idle time stats v2 nohz, procfs: introduce get_cpu_idle/iowait_time_coarse
