STRUCT 
TASK_CPUTIME(9)						   Driver Basics					    STRUCT TASK_CPUTIME(9)

NAME
       struct_task_cputime - collected CPU time counts

SYNOPSIS
       struct task_cputime {
	 cputime_t utime;
	 cputime_t stime;
	 unsigned long long sum_exec_runtime;
       };

MEMBERS
       utime
	   time spent in user mode, in cputime_t units

       stime
	   time spent in kernel mode, in cputime_t units

       sum_exec_runtime
	   total time spent on the CPU, in nanoseconds

DESCRIPTION
       This is an extension of struct cputime that includes the total runtime spent by the task from the scheduler point of view.

       As a result, this structure groups together three kinds of CPU time that are tracked for threads and thread groups. Most things considering
       CPU time want to group these counts together and treat all three of them in parallel.
