Description Roland McGrath 2004-12-14 04:15:22 UTC 
Description of problem:
The kernel's clock_* and timer_* interfaces need to be extended to support
clocks and timers tracking the CPU time used by processes and threads.
This is required for proper implementation of the _POSIX_CPUTIME and
_POSIX_THREAD_CPUTIME options at user-level.


Version-Release number of selected component (if applicable):
2.6.9

patch posted upstream to add CPU clock support to timer_* syscalls

This patch follows on the cpuclocks patch to add the timer part of the support.
Comment 3 Roland McGrath 2005-03-13 04:14:06 UTC 
My changes are in Linus's tree now, hopefully in 2.6.12
Comment 4 Roland McGrath 2005-04-24 01:11:00 UTC 
Rawhide 2.6.12rcN kernels have this.
Comment 5 Roland McGrath 2005-08-09 07:04:13 UTC 
All good in FC4.
