Hi all,
the 'result' field in the SCSI command is defined as having
4 fields. The top byte is declared as a 'driver_byte', where the
driver can signal some internal status back to the midlayer.
However, there is quite a bit of overlap between the driver_byte
and the host_byte, resulting in the driver_byte being used in
very few places, and mostly in legacy drivers.
Additionally, we have _two_ sets of definitions for the
last byte (status byte), which can specified either in SAM terms
or in the linux-specific terms, which are shifted right by one
from the SAM ones.
Needless to say, the linux-specific ones are declared obsolete
for years now.
And to make the confusion complete, both the status byte and
the driver byte have a byte for a valid sense code, resulting
in quite some confusion which of those bits to check.
This patchset does several things:
- remove the linux-specific status byte definitions, and use
the SAM values throughout
- replace the driver-byte values with either SAM ones (for sense
code checking) or host-byte definitions
- remove the driver-byte definitions
As usual, comments and reviews are welcome.
Please note, commit 66cf50e65b18 ("scsi: qla2xxx: fixup incorrect
usage of host_byte") from 5.4/scsi-fixes is a prerequisite for
this patch series.
Changes to v1:
- Include reviews from Finn Thain et al
- Make sysbot happy
