checking against nprocs is wrong in any case btw - we do allow
maxproc higher than number of current processes, it would just mean
no new process could be started until number of processes would
be lower than the new limit
Avoids a lot of casting and removes the need for some line breaks.
Removed a load of (caddr_t) casts from calls to copyin/copyout as well.
(approved by christos - he has a plan to remove caddr_t...)
- #ifdef out a DIAGNOSTIC printf() that was too annoying (rule of thumb,
don't make DIAGNOSTIC printfs() that print *very* frequently...)
- fix DIAGNOSTIC test that would always get triggered on a new session.
lookup and allocation, and any dependency on NPROC or MAXUSERS.
NO_PID changed to -1 (and renamed NO_PGID) to remove artificial limit
on PID_MAX.
As discussed on tech-kern.
having some #ifdef UNION code in vfs_vnops.c, introduce variable
'vn_union_readdir_hook' which is set to address of appropriate
vn_readdir() hook by union filesystem when it's loaded & mounted
Treat +ve numbers as process group ids and -ve as pids (see tcsetpgrp() in part of current session.
Treat +ve numbers as process group ids and -ve as pids - see tcsetpgrp(3).

syscall sys_timer_settime()) to take an absolute value for realtime
timers. This avoids a pair of gratiuitous conversions with the
possibility that the timer's intermediate value would be 0.0, which
would signal timer_settime() to cancel the timer.
Adjust callers of timer_settime() to compensate; catch the case where
sys_timer_settime() with an absolute time value of now and a virtual
timer would also be subtracted down to a timer-cancelling 0.0.
This should fix the bug seen in libpthread's nanosleep() where certain
applications, such as xmms, would wedge with unexpired userlevel
alarms.
people would read that list in a more timely fashion!), change the new
64-bit memory reporting sysctl nodes to report bytes. This should not
be a problem, since it's only a week old, and no applications use the
new nodes yet.
be returning because the code path that calls is will very likely call
setrunnable() again on the returned thread, leading to a panic because
the thread returned is already at LSRUN. This fixes a problem where netbsd
would panic when using gdb (5.3) on a process with multiple lwp's like this:
% gdb program
(gdb) run
^C
(gdb) quit
We cannot store LWP pointers permanently in lock structures, for two reasons:
1) They are somewhat ephemeral. Dangling pointers are bad.
2) A different LWP may issue the unlock, and in this case, we were not actually
doing the unlock at all. This was causing processes to exit without undoing
fcntl(2) locks. Furthermore, the locks are process-specific to begin with,
so the test was just plain wrong.
Instead, we go back to storing a proc pointer for POSIX locks. In addition, we
add an extra pointer to the LWP, which is used in deadlock detection. After
the lock is granted, this pointer is 0ed and there is no reference to the LWP.

and in libkvm. Then teach ps how to show them to you.
Also, teach ps how to show the names for all the uids, the rest of the
group numbers, and the "group access list".
this alignment would have been backward into the dataspace covered by
MAXDSIZ. Now the alignment is done forward. XXX It is expected that
in the TOPDOWN case, VM_DEFAULT_ADDRESS will make sure any address it
returns has the proper alignment for that architecure.
psection alignment. XXX If the psection alignment is greater than the page
alignment, extra pages may be mapped that will never be needed. This is
inefficient and wasteful of swap space and needs to be fixed.
VM_DEFAULT_ADDRESS from elf*_makecmds to elf*_load_file. In load_file,
actually determine ahead of time how much space will be needed and pass
that to VM_DEFAULT_ADDRESS. Now we have a relatistic starting address
so we can do the loading of psections normally with no extra topdown
code in load_psection. Also, if there is a gap in betweeen psections
zero map an inaccessible region between (just like ld.elf_so does) to
avoid inadvertant mmaps in the gap.
