path so that ERR_load_strings() is found in certain circumstances
involving dlopen(). eg: main program dlopened foo.so which is linked
against libcrypto. If libcrypto then dlopens librsaUSA.so, then it's
search path doens't find libcrypto (!). One "fix" is to force
modules (eg main opening foo.so) to use the RTLD_GLOBAL flag, the other
is to explicitly declare dependencies (as done here).
is responsible for this and this will lead to malloc 'freeing already
free' type panics. One was in the probe code, the other was in the
pccard eject? code.
Not explicitly approved by: jkh (but the first is fallout from subr_bus.c
rev 1.54 which was an approved commit, the second is the same problem)
adw_pci.c:
Update comments describing supported chips/cards.
adwcam.c:
adwlib.c:
adwlib.h:
Handle more error return codes from the firmware.
Break out the bus reset code into its own function.
Usa a constant for the bus reset hold delay.
Fix an interrupt race problem in adw_idle_cmd_send by
incorporating the poll loop for command completion.

to us, subr_bus.c will free it. This bug (panic: freeing already free)
was exposed by kern/subr_bus.c rev 1.54
Not explicitly approved by: jkh (but this is a showstopper and fallout of
the above approved change)
transferred, do it in complete_rqe instead.
launch_requests: Replace the inadvertently removed splbio() around the
main loop. It may not be necessary, but the biggest
test of this stuff are IDE disks, which I'm not
using.
Remove throttling code, I'm pretty sure it's not
needed any more.
Don't set B_ORDERED, it's not necessary either.

build_rq_buffer: Don't lose the B_ORDERED bit, it still has some
residual meaning. To do this right, Vinum needs to
look at the B_ORDERED bit and order the transfer
across all disks involved. That's an exercise for
another day.

Describe stop -f to stop when config updates are disabled.
Explain in more detail why Vinum needs its own partition type, and why
you can't make it the c partition.
Implicitly-sanctioned-by: jkh
The driver constructs a fake disklabel that makes the 'a' partition
cover the entire DVD-RAM disk. This cannot be changed from the user
side. This solution was chosen because most DVD-RAM will have a
UDF (or until we have that CD9660) filesystem on it covering the
entire disk, its not really thought as a real random access device.
This might change over time, but for now this is what we have, and
it is compatible with CDROM's etc, that makes using the minidisk
subsystem less than ideal, because of !modulo BDEV_SIZE blocks.
