if the 'time on a node is 0,..
tell the world it is the same as 'boottime'.
This is becasue 'time' is not set up when we create the nodes,
so we can't set them then.
Added CONTROL device that only does user-ioctl and nothing else;
Added protection so user-ioctl requires write access;
Clean up scsiconf.h a little. It needs more work.
the lookup fails. Updated callers to deal with this. Call in_pcblookuphash
instead of in_pcblookup() in in_pcbconnect; this improves performance of
UDP output by about 17% in the standard case.
space for the hash list buckets and is a little faster. The features
of tailq aren't needed. Increased the size of the object hash table
to improve performance. In the future, this will be changed so that
the table is sized dynamically.
as side-effect, removed some legacy code that was necessary
when we called vm_fault inside of vm_fault_quick instead of using
the kernel/user space byte move routines.
(2GB). If this limit is not imposed, then filesystem corruption will
ensue when files larger than 2GB are created. This is temporary,
and the underlying limitation will be removed later.
algorithm is used on aic7770 Rev E or higher chips to improve perfomance.
This required a hardware change but we don't know exactly what (most
likely some special register to do fast SCB indexing into host memory),
and we are not at all sure that there are more than 4 SCBs on these
chips. This probe will still classify the revision of the aic7xxx, but
we now default to 4 SCBs (at least until we know more of what was done).
This also fixes a bug in the timeout routine where we cleared a flag
too soon making it imposible to enter one section of the routine.

interrupts to zero to start with. This is the value we return in
most cases. The sense code then outbs the apropriate value to cause
sense retrieval. The return value was uninitialized before this
change (something that was an okay thing with the old sequencer code,
but not with the semantics of the new).
This problem caused us to always retrieve sense upon recieving a non
zero status byte. This is exactly what was happening for the "target
busy" status returned by exabyte tape drives when they rewind or
power on with a tape installed. The request sense proved fatal.
This should fix the tape problems.
but it outlines what I'm GOING to do to this file.
It's sort of an unignorable notification of coming changes..
This is a bit rude I understand.. but I can't afford to haqve the
diskslice code drifting off too much further from a workable system
and I think I need to jump in now to make it obvious what has to be done
before it's too late.
appologies to bruce in advance.
bin/stty. Define alias CCAR_OFLOW for MDMBUF.
Declare speeds as having type speed_t instead of long. speed_t is
long, which is wrong (POSIX specifies it to be unsigned integral),
but fixing it might introduce more serious bugs.
user-level part has already been commited.)
Note that i've lost the "official" code for this; it went into the
system after 1.1.5.1. The commited code is my own version, but it has
proven to work for me for more than a year now.
if an invalid ioctl is done on /dev/klog. logioctl() needs to return
an errno instead of -1 on a failed ioctl.

This submission was done by hand-applying FreeBSD local modifications on
top of the UCB code, rather than trying to patch the UCB code in on top
of the FreeBSD code due to the extensive changes.
