Subject: [PATCH 0/3] de_thread() should update ->real_start_time
Date: Mon, 10 Jun 2013 20:33:00 +0200 [thread overview]
Message-ID: <20130610183300.GA14379@redhat.com> (raw)
1/3 is the obvious bugfix, 2 and 3 are minor cleanups
I am wondering, can't we kill task->real_start_time? What if we
simply change copy_process
- do_posix_clock_monotonic_gettime(&p->start_time);
+ get_monotonic_boottime(&p->start_time);
?
Afaics, this will only affect do_acct_process() and bacct_add_tsk(),
but do we really want to exclude the suspended time in this case?
Another user of ->start_time is cgroup.c and it looks wrong... But
the change above should not make any difference.
Oleg.
