From: Tatsuhiro Aoshima <tatsu.pc@gmail.com> Subject: [PATCH] proc: let task status file print utime and stime.
The task status file in proc file system did not contain user-time and system-time. Thus, users could not get those information of running task easily. I think these values should be provived in human readable format. By this patch, users can get stime and utime very easily.
