That's EVERY SINGLE driver that has an entry in conf.c..
my next trick will be to define cdevsw[] and bdevsw[]
as empty arrays and remove all those DAMNED defines as well..
Each of these drivers has a SYSINIT linker set entry
that comes in very early.. and asks teh driver to add it's own
entry to the two devsw[] tables.
some slight reworking of the commits from yesterday (added the SYSINIT
stuff and some usually wrong but token DEVFS entries to all these

BTW does anyone know where the 'ata' entries in conf.c actually reside?
seems we don't actually have a 'ataopen() etc...

ifp->if_output() functions. This way, initial implementations of
rt_output functionality can just lazily use if_output until customized
versions are written.
(mask,value) in the tree, don't immediately return EEXIST. Instead, check
to see if the pre-existing route was generated by protcol-cloning. If so,
then it is OK to simply blow away the old route and re-attempt the insertion.
If not, then fall back to the same error code as before.
for the same reasons as in slclose().
Free the cblock in the canonical queue in pppclose(). This is a no-op in
the usual cases where the tty is being closed or the line discipline is
being switched back to the standard discipline, but it saves a cblock if
the line discipline is being switched to one that doesn't use the canonical
queue.
Add prototypes. I use `extern' in prototypes for functions with bogus
linkage. This should be fixed someday.
Continue cleaning up new init stuff yet again.
Fix loopback and discard interfaces to understand BPF writes.
(These two from Bill Fenner to fix PR 512.)
Move ifpromisc() from bpf.c to if.c as suggested by comment in BPF.
Send a notice to the log when promiscuous mode is enabled.
in pppstart(), the output process may be overloaded to handle hardware
flow control and hardware output completions.
Don't wait for output to drain in slclose(). Discard output immediately.
New output is not prevented while processes are waiting for output to
drain (this is a bug), so the wait was sometimes forever. Infinite
waits are also possible when CCTS_OFLOW is enabled and CTS is down.
Infinite waits were also caused by the above bug in slstart().
Start changing new init stuff yet again: rename unused arg `dummy'.

This is a composite of 3 patch sets submitted by terry.
they are:
New low-level init code that supports loadbal modules better
some cleanups in the namei code to help terry in 16-bit character support
some changes to the mount-root code to make it a little more
modular..
NOTE: mounting root off cdrom or NFS MIGHT be broken as I haven't been able
to test those cases..
certainly mounting root of disk still works just fine..
mfs should work but is untested. (tomorrows task)
The low level init stuff includes a total rewrite of init_main.c
to make it possible for new modules to have an init phase by simply
adding an entry to a TEXT_SET (or is it DATA_SET) list. thus a new module can
be added to the kernel without editing any other files other than the
'files' file.
Call output process whether or not there is any output. The output
process may be overloaded to handle hardware flow control and
hardware output completions.
Introduce TS_CONNECTED and TS_ZOMBIE states. TS_CONNECTED is set
while a connection is established. It is set while (TS_CARR_ON or
CLOCAL is set) and TS_ZOMBIE is clear. TS_ZOMBIE is set for on to
off transitions of TS_CARR_ON that occur when CLOCAL is clear and
is cleared for off to on transitions of CLOCAL. I/o can only occur
while TS_CONNECTED is set. TS_ZOMBIE prevents further i/o.
Split the input-event sleep address TSA_CARR_ON(tp) into TSA_CARR_ON(tp)
and TSA_HUP_OR_INPUT(tp). The former address is now used only for
off to on carrier transitions and equivalent CLOCAL transitions.
The latter is used for all input events, all carrier transitions
and certain CLOCAL transitions. There are some harmless extra
wakeups for rare connection- related events. Previously there were
too many extra wakeups for non-rare input events.
Drivers now call l_modem() instead of setting TS_CARR_ON directly
to handle even the initial off to on transition of carrier. They
should always have done this. l_modem() now handles TS_CONNECTED
and TS_ZOMBIE as well as TS_CARR_ON.
gnu/isdn/iitty.c:
Set TS_CONNECTED for first open ourself to go with bogusly setting
CLOCAL.
i386/isa/syscons.c, i386/isa/pcvt/pcvt_drv.c:
We fake carrier, so don't also fake CLOCAL.
kern/tty.c:
Testing TS_CONNECTED instead of TS_CARR_ON fixes TIOCCONS forgetting to
test CLOCAL. TS_ISOPEN was tested instead, but that broke when we disabled
the clearing of TS_ISOPEN for certain transitions of CLOCAL.
Testing TS_CONNECTED fixes ttyselect() returning false success for output
to devices in state !TS_CARR_ON && !CLOCAL.
Optimize the other selwakeup() call (this is not related to the other
changes).
kern/tty_pty.c:
ptcopen() can be declared in traditional C now that dev_t isn't short.
interface is no longer IFF_UP.
The test for IFF_UP in ifpromisc is only useful while enabling IFF_PROMISC
and the higher levels of the bpf code do not allow for the possibility of
failure while shutting down. This is a trivial change.
Also, fixes PR#522.
Remove nullmodem().
It may be useful to have a null modem routine, but nullmodem()
wasn't one. nullmodem() was identical to ttymodem() except it
didn't implement MDMBUF (carrier) flow control, didn't do any
wakeups for off to on carrier transitions, and didn't flush the
i/o queues for on to off carrier transitions (flushing has the side
effect of waking up readers and writers) although it did generate
SIGHUPs. The wakeups must normally be done even if nullmodem() is
null in case something is sleeping waiting for a carrier transition.
In any case, the wakeups should be harmless. They may cause bogus
results for select(), but select() is already bogus for nonstandard
line disciplines.
Kernel PPP doesn't pay attention to IPTOS_LOWDELAY, but uses
a table of port numbers, which isn't a generic method. The following
patch fixes this (the table is still used, but in addition
PPP queues the packet in fastq if IPTOS_LOWDELAY is set.

Clean up the recently added code:
- include the appropriate header to declare an implicitly declared function.
- declare timeout functions correctly and remove numerous bogus casts that
hid (but didn't fix) their incorrectness.
In rare cases, when the filter specified accesses an multi-byte value that
is split across mbuf's, the value loaded is incorrect. And if you are very
unlucky (like me) it will index off the end of the mbuf and into an
unallocated page and panic the system.
If you look at the code you will discover the the index *k* is added to

It is common case when modem hangs with carier on but don't

This thing commonly healed with hangup and redialing.
Enhancements below allows to determine when such action
is needed and inform attach program with SIGURG signal.
There two ioctls set: outfill and keepalive, used from both
sides of connection. Outfill repeatedly sends FRAME_END with
specified timeout (i.e. 40 seconds). It is needed to get input on
other side even if no user activity on slip line currently.
Keepalive checks FRAME_ENDs from other side, and if no one
got in specified timeout (i.e. 60 seconds, max modem retrain time),
send SIGURG to attach program.
I plan to add code to slattach to handle this thing too.
