Comment:
This patch adds support for OSF Mach, which doesn't have creation_time in `struct
task_basic_info', by adding a member creation_time to `struct procinfo'. It is
initialized by proc when a `struct proc' for the task is allocated and kept in this
`struct proc'.
A configure function is still needed to detect if this should be enabled.

Hi,
the creation time was an invention of us, and he put it into GNU Mach 1999. This
seemed to be an easy change. Instead changing the Hurd to allow for the lack of it,
can't you backport our change to OSF Mach? Here are the relevant changelog entries
from GNU Mach:
1999-05-29 Roland McGrath <[EMAIL PROTECTED]>
* kern/startup.c (start_kernel_threads): Call record_time_stamp to
reset the kernel task's creation_time field, so it's not zero.
1999-05-23 Roland McGrath <[EMAIL PROTECTED]>
* kern/task.c (task_info): Allow count for TASK_BASIC_INFO to be less
two words, not just one. The new member creation_time is two words.
Wed Aug 20 16:05:19 1997 Thomas Bushnell, n/BSG <[EMAIL PROTECTED]>
* kern/thread.h (struct thread): New member `creation_time'.
* include/mach/thread_info.h: New member `creation_time'.
* kern/thread.c (thread_create): Set creation time stamp.
(thread_info) [THREAD_BASIC_INFO]: Fill in new creation time
field. Carefully preserve compatibility with old callers.
* kern/task.h (struct task): New member `creation_time'.
* include/mach/task_info.h: New member `creation_time'.
* kern/task.c (task_create): Set creation time stamp.
(task_info) [TASK_BASIC_INFO]: Fill in new creation time field.
Carefully preserve compatibility with old callers.
* kern/mach_clock.c (record_time_stamp): New function.
* kern/time_out.h (record_time_stamp): Add prototype.

Comment:
I already wondered why the OSF Mach developers would have wanted to remove it... 8-)
I'll try to change it in Mach; I wanted to start working on Mach anyway, since it has
at least one other annoying bug and the hurdppc project on savannah.nongnu.org also
needs a version of Mach that runs on newer PPC computers (using OSKit). It'll
probably take some time, however.
