It closed the wrong device (usually the B partition instead of the C
partition).
It closed a device without having opened it.
It didn't open a device often enough. This caused swap partitions on
slices other than the first slice looked at to be unavailable for swapping.
It didn't check the device number sufficiently.
Reopen the bdev for the raw partition and not the cdev if only the bdev
was open.
Don't use a bogus limit for the number of partitions to possibly reopen
(bug found by Julian).
Add function dssize() to help fix wdsize() and sdsize(). The slice
layer knows more about (un)open partitions and partition sizes than
the driver layer.
Remove silly "Naffy, the Wonder Porpoise" attribution and add more
justifiable (and overdue) attribution to Bruce Evans. Look at it
as a delete and add operation batched together, not a substitution. :-)
notice, performed all of the structural changes necessary to get this thing
to work with the unidirectional-DMA version of voxware.
This work is -not- complete, but it's in far better shape than it was, and
I may not touch it again for another few months.
in read() and write(). FNONBLOCK is valid in ioctl() and close().
The bug caused hung ptys when a process talked to itself using nonblocking
i/o and exited while the slave pty had output to flush. ttywait() was
called and hung. Signals didn't work because the process was exiting.
`comcontrol /dev/ttyp0 drainwait 1' worked to terminate the wait. This
shows that comcontrol is not limited to hardware control. It has no i386
or driver dependencies and doesn't belong in src/sbin/i386.

to emit spurious page outside of object type messages. It is not
a fatal condition anyway, so the message will be omitted for
release. Also, the code that "clips" the allocation size, associated
with the above problem, was fixed.
The ``flags 1'' in the fdc line is now only needed for owners of an
Insight tape (perhaps there aren't any? Mine is disfunctional). All
other probes are safe wrt. to the motor-control line of floppy disk
drives. Document the flag in LINT finally.

Added support for Cogent em100 boards.
Fixed bug that caused BPF to toggle the card to UTP.
Various other improvements.

Change IPTOS_PREC_ROUTINE to 0 (was conflict with IPTOS_LOWDELAY) according
to RFC 791 (unchanged since it) and BSDI 2.0 style

initializing proc0's frame base, too, using cpu_set_init_frame(). It's
a kludge because that macro is intended to be used only for init, but
does what we want nonetheless.

worm.o: Undefined symbol `_STUNIT' referenced from text segment
I copied the STUNIT definition from the old scsiconf.c into this file to
work around this problem.
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.
