- Request the maximum number of LUNs on a device if it is
a Bulk-Only device.
- Handle NO_TEST_UNIT_READY case for SCSI
- Add NO_START_STOP quirk for LS-120
- Fix a KASSERT which was the wrong way around.
- Kickstart the LS-120 with the infamous LS-120 specific command of
which no one knows what it doesn, apart from the fact that it appeared
in the Linux code someday.

I'm running with this change right now and have seen no negative
side-effects.
On my sytem this reduced kernel BSS by about 25KB.

kernel. Justin agress that there is no other reasonable alternative to
do automatic rescans on connect.
The problem is that when a new device attaches to a SIM (SCSI host
controller) we need to send a XPT_SCAN_BUS command to the SIM using
xpt_action. This requires however that there is a peripheral available
to take the command (otherwise xpt_done and later bomb). The RESCAN
ioctl uses the same periph.
This enables a USB mass storage drive to do an automatic rescan on
connection of the drive.
The automatic dropping of a CAM entry on disconnection was already
working (asynchronous event).
The next thing to do is find someone to commit a change to vpo to do the
same thing. Just port umass_cam_rescan and friends across to that
driver.

it's unlikely that any solution they may come up with will involve
the use of mktemp(1).

Move b_offset, b_data and b_bcount to struct bio.
Add BIO_FORMAT as a hack for fd.c etc.
We are now largely ready to start converting drivers to use struct

Use a separate buffer for command transforms instead of fiddling with

Take CAM_CDB_POINTER into account. Nobody is using it, but someone might

special device. This fixes the breakage that occured when trying to
dump a filesystem by name (e. g. /usr), with an fstab already
mentioning the raw device name (like /dev/rda0g) where dump attempted
to use /dev/rrda0g then.
Also removed the now obsolete remark that fstab were carrying block
special names.
introduced in FreeBSD-4.0. The driver is now full up-to-date
with regards to the current kernel interfaces.
Another significant change in this driver version applies
to the checking of the data direction. The driver is now
able to check against the expected data direction in any
circumstance and will not hang either if direction is wrong
at the start of the IO, or if for some weird reason,
the device changes to the wrong direction during the IO.
This driver version is still usable under FreeBSD 3.2/3.3,
since it only requires CAM, other kernel interface dependencies
being #if'ed in the sources according to kernel version.
But, in order to use the driver under those early kernel
versions, user has to move the driver sources by hand and make
appropriate tiny changes to let the kernel know about the driver.
Other changes:
- Remove the debugging stuff for WSR bit.
- Get rid of some warnings about volatile being discarded.
