16 utime
17 time spent in user mode, in cputime_t units

19 stime
20 time spent in kernel mode, in cputime_t units

22 sum_exec_runtime
23 total time spent on the CPU, in nanoseconds

26 This structure groups together three kinds of CPU time that are tracked
27 for threads and thread groups. Most things considering CPU time want to
28 group these counts together and treat all three of them in parallel.
