confusing when trying to attach scsibus to a hba, since it is really meant
for attaching scsi devices to scsibus.

asc/ascq handling to deal with the pair together rather than seperately, since
modern scsi has long since polluted the "categories" of asc enough that you
pretty much need to always look as ascq.

scsi devices. the midlayer keeps some state for each device that is
attached which needs to be cleaned up on detach, hence this wrapper.

0, not NULL.

for walking the bus and targets, and probing the luns. this removes the
need to use magic numbers to wildcard each of these, which in turn makes
the code a lot easier to read. as a bonus we get some more space to work in
(80 chars isnt that much somtimes).
note that this code wont probe high luns if lun 0 doesnt exist.

"becoming ready" - this is done in the exact same way that it
was done for tape in st.c. This commit adds a cd specific interpret_sense
routine to cd.c that will catch the becoming ready case and handle it.
This also removes the need to use crazy timeouts to catch this case.

floppies and cd's were removable, displaying that fact in disklabel
output was unlikely to help. And the display in disklabel was the only
use of D_REMOVABLE in the tree.

when they need a process context to do something. the most obvious task
that springs to mind is attaches and detaches of devices on scsibus.

struct for it and keep it in the midlayer. however, this struct was never
free'd on detach.
since we only do hotplugging of controllers (and the scsibus and devices
get hotplugged as a matter of course), we now walk the list of scsi_link
structs and free them on detach of scsibus.

when using removable media devices, along with changes to scsi_base to
detect such cases in tapes other devices. This makes tar, dd, and friends
report a semi useful error message instead of nonsense when there is nothing
in the device.
Includes libc minor bump, and will require the corresponding sets change.

that specifies the version of SCSI being supported. Even the ANSI part
that we use is complex. 4 means 2, 5 means 3 and 6 means 4. Translate
and use the value correctly. Fixes SCSI5 and SCSI6 in dmesg. And
properly protects SCSI2 devices from getting SCSI3 commands.

obtained probe the LUNs given without checking for duplicate INQUIRY
data.
For non-USB, non-ATAPI, devices claiming to be SCSI-3 compliant. And
the target must have something attached at LUN 0.
If REPORT LUNS can't be used or isn't supported, the old scan process
is used.
Fixes Fibre Channel and SCSI enclosure devices that provide identical
INQUIRY data for all LUNs and were thus being misprobed as having
only LUN 0.
Tested by Bob Kitella, dlg@, beck@. Suggestions from deraadt@.

|

LUNs the driver says targets could have. Don't unconditionally
allocate 8. USB and ATAPI devices have fewer. Fibre Channel devices
can have more.

valve in case our duplicate LUN checks had to be circumvented. Since
no one has found a need for them, and they were just one more place
trying to shift a bit 255 places to the left could be induced, remove
them.

when we're not allowed to yank things out of them. Instead of returning a
generic EIO and having the kernel printf a scsi sense to the console,
we now return EBUSY to userland and avoid the dmesg spewing.

diagnostic type printf spew that is useful into #ifdef CHANGER_DEBUG,
removes some that is pretty much useless, and changes one instance
of using kernel printf to indicate the truncation of a result due to the
provided buffer being too small into a return of EINVAL back to the caller.

Eliminate the quirks, etc. used to store info on these non-existant modes.
Also eliminate a couple of 'unimplemented' fields in the ioctl request
structure.
