            Bug ID: 26397
           Summary: Modern kernels no longer use cputime for task->utime
                    and task->stime
           Product: systemtap
           Version: unspecified
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: tapsets
          Assignee: systemtap at sourceware dot org
          Reporter: agentzh at gmail dot com
  Target Milestone: ---

The task_time_string() tapset function assumes task->{utime,stime} to be
cputime (or jiffies), which leads to very wrong results being returned. Modern
kernels already use nanoseconds for these two fields.
