[PATCH v2 3/3] process cputimer is moving faster than its corresponding clock

2013-04-26 Thread Olivier Langlois
Add thread group delta to cpu timer sample when computing a timer expiration. This is mandatory to make sure that the posix cpu timer does not fire too soon relative to the process cpu clock which do include the task group delta. test case to validate the patch is glibc-2.17/rt/tst-cputimer1.c
