the sd & od drivers. There is also slight changes to fdisk & newfs
in order to comply with different sectorsizes.
Currently sectors of size 512, 1024 & 2048 are supported, the only
restriction beeing in fdisk, which hunts for the sectorsize of
the device.
This is based on patches to od.c and the other system files by
John Gumb & Barry Scott, minor changes and the sd.c patches by
me.
There also exist some patches for the msdos filesys code, but I
havn't been able to test those (yet).

medium with another size is being inserted. Right now, this case was
broken and led to a situation where a medium could only be replaced
with another one of the same size.

calls Debugger() and returns without setting bp->b_error.
This can happen when there is a casting error and offsets > 2G are
converted to negative off_t's in the disk tools. (dumpfs used to do this).

. introduce an option OD_AUTO_TURNOFF
. try to use the native geometry as reported by the drive instead of
a faked on -- MOs do have a ``classical'' geometry

Changed DEVFS structure devfs_token so that adding the devices is
a simple matter of a 4 line for loop versus 16 lines of code
Reviewed by: julian@freebsd.org
Added scsi control devices.
Converted almost everything that I changed to use devfs_add_devswf()
and verbose id macros.
st.c:
Renamed enrst* to erst* since that's what the current name is (enrst
seems to be an old name).
drives require ST_Q_SNS_HLP, they also wrongly accept a blocksize of
1024 in the first place (for a QIC-150 cartridge), but complain later
about it. The hack is to only probe for 512 for them.
Reorder the entries in st_decide_mode() so that QIC >= 525 is properly
accepted as variable blocksize.
. remove some unused variables
. declare worminit() right this time, it's actually extern (?)
. use wormminphys(), now that it's already there (hope i've got this right)
Also declared worminit() to avoid a compiler warning. Seems that the
other SCSI drivers don't declare XXinit() yet, so perhaps we'd also
create a typedef for these func's.
The worm driver is alpha-usable! I've stuffed everything that is
needed into the kernel driver, including the logic to select
between different vendor's quirks.
Disclaimer: this has by now _only_ been tested on a heavily tweaked
2.0.5R system. I've done my best to retrofit it into -current, but
i don't have a chance yet to test it in a -current environment.

Added bdev and cdev args to dsopen().
drivers:
Fixed device names, links, minor numbers and modes.
wd.c:
Started actually supporting devfs.
diskslice.h:
Added devfs tokens to structs (currently 576 of them per disk! :-().
subr_diskslice.c:
Create devfs entries in dsopen() and (unsuccessfully) attempt to make
them go away at the right times. DEVFS is #undefed at the start so
that this shouldn't cause problems.
This makes it sorta usable, just for my ``proof-of-concept'' Perl
script i've been posting to freebsd-scsi. The driver will be
overhauled further, this is just to provide Jordan with a base to
perform testing of his own with his HP burner. Use entirely at your
own risk, expect a bunch of misburnt CD-R's when using it already in
this very green stage.
Note that by now the driver will only work when the CD-R has already
been in the drive at boot time.

While i was at it, i've removed two bogus channel numbers in the``set

Also remove Julian's misspelling of `stereo'.
