doesn't have a process group, which can occur if you're working with
a custom init that doesn't set up a full tty context. Rather than
refusing to reboot, ignore ESRCH from the kill attempt in reboot(8).
event posting functions varargs to fill these.
Attribute g_call_me() to appropriate g_geom's where necessary.
Add a flag argument to g_call_me() methods which will be used to signal
cancellation of events in the future.
This commit should be a no-op.
print a warning, and set the idletime variable for the entry to -1;
then pick up the -1 later in sprint() and lprint() and ignore those
idle times by printing just whitespace. When third party applications,
such as kdm, insert utmp entries, they sometimes use strings like ":0",
which can't be stat()'d and currently result in warnings that are
not helpful to the user.
This patch is rather big because I had to significantly redesign
the driver to make the busdma conversion possible. Most notably,
hardware and software structures were carefully splitted to get
rid of all the structs overlapping evilness.
Special thanks to phk and Richard Puga <puga@mauibuilt.com> for
providing me with fxp(4) hardware to do this work.
Thanks to marcel for testing this on ia64, and to Fred Clift
<fclift@verio.net> for testing this on alpha.
Tested on: i386, ia64, alpha
KASSERT the race between close and strategy, it is an error in the upper

Add XXX: comment explaining why the ioctl/orphan race is not closed.
to select a KSE with a slice of 0 we will update its slice and insert it
onto the next queue.
- Pass the KSE instead of the ksegrp into sched_slice(). This more
accurately reflects the behavior of the code. Slices are granted to kses.
- Add a function kseq_nice_min() which finds the smallest nice value
assigned to the kseg of any KSE on the queue.
- Rewrite the logic in sched_slice(). Add a large comment describing the
new slice selection scheme. To summarize, slices are assigned based on
the nice value. Priorities are still calculated based on the nice and
interactivity of a process. Slice sizes of 0 may be granted for KSEs
whos nice is 20 or futher away from the lowest nice on the run queue.
Other nice values are scaled across the range [min, min+20]. This fixes
ULEs bad behavior with positively niced processes.
_get_curthread(). This is similar to the kernel's curthread. Doing
this saves stack overhead and is more convenient to the programmer.
- Pass the pointer to the newly created thread to _thread_init().
- Remove _get_curthread_slow().
set_mcontext.
- Don't make assumptions about the alignment of the mcontext inside of the
ucontext; we have to save the floating point registers to the pcb and then
copy to the mcontext.
This was changed because originally we were blocking on the umtx and
allowing the kernel to do the queueing. It was decided that the
lib should queue and start the threads in the order it decides and the
umtx code would just be used like spinlocks.
doing Limited Transmit. Only artificially inflate the congestion
window by 1 segment instead of the usual 3 to take into account
the 2 already sent by Limited Transmit.

Retain the mistake of not updating the devstat API for now.
Spell bioq_disksort() consistently with the remaining bioq_*().
#include <geom/geom_disk.h> where this is more appropriate.
