stack, is currently set to 25%. With 25% battery left, a typical
modern laptop will have at least one hour runtime left. It is an
arbitrary value, and other APM power layers in the kernel set CRITICAL
to something like 5% or 10%, so set it to 10% for now.

interrupt line register as the irq number doesn't really work as the contents
of that register might be 0, and the code has checks for non-zero irq
numbers in places. Insteadmake drm_dev_to_irq() return -1, which is an
obviously bogus, but non-zero value.
This should fix inteldrm(4) on recent Apple hardware.

As Kenjiro Cho pointed out it is very hard to cancel a dequeue operation
for some queueing disciplines when such it keeps some internal states.
As you can see, APIs can also Live Fast & Die Young.

Return EAGAIN in this case:
# vmmctl -d
vmmctl: disable VMM command failed (35) - Resource temporarily unavailable
ok mlarkin@

Currently one MUST do "vmmctl -e" before creating a vm with "vmm -S ...".
Lately this could be done automagically by vmd(8) but the kernel should
not allow things that wont fly.
While here, disable vmm mode in error path if at least one of the CPUs
failed to enable it.

dont check if its busy at all, actually.

with pledge_socket(p, -1, state) we only check for "dns" promise against SS_DNS
socket. But it isn't possible to pass a SS_DNS socket to listen(2) or accept(2)
(EINVAL). So this deeper check is a bit useless...

hfsc needed a rollback ifqop to requeue the mbuf because it used
ml_dequeue in the begin op. now it uses MBUF_LIST_FIRST to get a
ref to the first mbuf in deq_begin.
now the disciplines dont need a rollback op, so ifq_deq_rollback
can be simplified to just releasing the mutex.

MBUF_LIST_FOREACH is then rewritten on top of those.
this makes it easier to get at the head of a list too, which may make
the hfsc ifq backend nicer.

also. The idea is much like rpath is with files, you get an fd and then
you can play with it somewhat. In the socket space once you have a fd, you
can play with it somewhat. So you cannot bind, but you can accept. You
can listen, getpeername, getsockname, and of course set/getsockopt is
somewhat available.. yes, this makes pledge the anti-capsicum, kind of
like salt from Secovlje.. reasoning due to a conversation with tedu

few disklabel ioctls, and the DIOCMAP ioctl against /dev/diskmap used
to translate duid numbers into partitions.
This will allow pledging of at least 12 disk/filesystem aware
programs; due to the negative impact that diff will wait a bit so
everyone has a chance to update their kernels.

A piece is still not right as many peole reported a "watchdog timeout"
problem.
This basically brings us back to r1.305.

Allows us to get rid of mq_requeue(9) and IFQ_POLL(9) because wireless
drivers use a special queue for management frames.

The thread detaching an interface will sleep until all references to this
interface have been released. So we decided to only keep references for
a short period of time.
Keeping if_ref() private will hopefully help preserve this goal as long
as it makes sense.
Calling if_get()/if_put() in the same function also allows us to make
use of static analysis tools (thanks jsg@!) to catch our errors.

once you enqueue an mbuf, you no longer own it. therefore you cant
read the length out of it. this reads the length first, then tries
to enq it.
also, call if_start instead of a bare call to the underlying start
routine.

check. You cannot open a socket in a domain unless permitted -- but
you need to be able to accept one if the code flow asks for that to
happen. The most recent check is too tight. We may need to iterate the
policy here until we hit the right vibe...

only a driver sets or clears OACTIVE. clearing it without setting it is
a waste of time.
|

only a driver sets or clears it, and trunk never sets it. therefore it
never needs to clear it.

only a driver sets or clears this flag. pppx never sets it, so it
