Hi
This is a rework of my v2 series taking into account Paul
Turner's comments. All the series is the same except for
the patch that collets nr_switches that is now completely reworked.
It is out of schedule(), relegated to a scheduler hook. Only difference
from Paul's suggestion is that I added a new one, instead of messing with
put_prev_task + pick_next_task pairs. In the patchset that adds it,
I'll try to argue for my solution.
Hope this is acceptable, and please let me know of any other concerns.
v2:
* completely reworked nr_switches gathering
* separated per-se sleep_start to be more clear about it
Glauber Costa (6):
measure exec_clock for rt sched entities
account guest time per-cgroup as well.
expose fine-grained per-cpu data for cpuacct stats
add a new scheduler hook for context switch
Also record sleep start for a task group
expose per-taskgroup schedstats in cgroup
