Subject: sched_debug: runnable tasks sum-sleep

Hi,

i am looking for document to understand the output of "cat /proc/sched_debug":

..
runnable tasks:
            task   PID         tree-key  switches  prio
exec-runtime         sum-exec        sum-sleep
----------------------------------------------------------------------------------------------------------
..

i tried to search for the document to understand the meaning of each
field like, i did not get any.

could you please point any doc or help me to understand sum-sleep?

i got following info so far:

exec-runtime: se-> vruntime; virtual run time used for scheduling calculation
sum-exec: se-> sum_exec_runtime (actual running of physical time);
sum-sleep: Finally add belongs cgroup; se.sum_sleep_runtime

i am having doubt if sleep time is amount of time process was in sleep state?

thanks,
manish
