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.

we now return EBUSY to userland and avoid the dmesg spewing.

SENSE BIG command even if no page data was returned. Just accept the
fact that the device does not have any such page data.
This is more in line with the spec, and unbreaks devices (like the
Neodio 8-in-1 USB Card Reader donated by Manuel Pata) which freak out
when getting a MODE SENSE BIG.
Should not break any 'working' device.

Makes the logic simpler by eliminating the XS_BUSY dance in xs->error,

certain conditions.
Allow SCSI_NOSLEEP commands to be retried without waiting. Who knows,
they may work even without a delay.

so eliminate code dealing with 16 byte block descriptors. No one else
seems to use them anyway. Add define for appropriate permission bit in
case we ever need it.
Simplify and clean up scsi_do_mode_sense() code as a result.
Strengthen check to ensure block descriptor data is a valid by
checking if it is a multiple of 8 bytes rather than just > 8 bytes.
Moves code to closer to what it was before scsi_do_mode_sense().

required number of bytes, rather than a full scsi_mode_sense_buf. Some
devices (e.g. my HP SureStore DAT/24) decline to accept such oversized
transfers. Instead, force callers to fill in the data_length field in
the header and use that information to set the size of the transfer.

return the correct values for density, block_count and block_size
based on the type of the device. First cut has T_SEQUENTIAL (i.e.
tape devices) as the only device type using general block descriptors,
so the behaviour change is minimal.

Add 'big' parameter to report which mode sense header type is being

Convert sd_scsi.c to use new mechanism for non-optical drives. USB
