This patch series is the first batch of cleanups in an attempt to make
the SCSI printing more consistent and suitable for human consumption.
Previously a typical error looked like this:
sd 0:0:0:0: SCSI error: return code = 0x08000002
sda: Current: sense key: Aborted Command
Additional sense: Logical block reference tag check failed
You had to have the magic return value decoder ring handy to figure
out what had really happened. And you had to do the mapping between
sd 0:0:0:0 and sda yourself.
The following patches clean up various bits so that the same
information can be presented in a more readable form:
sd 0:0:0:0: [sda] Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE,SUGGEST_OK
sd 0:0:0:0: [sda] Sense Key : Aborted Command [current]
sd 0:0:0:0: [sda] Add. Sense: Logical block reference tag check failed
All printk's from sd.c now have the same prefix. If logging is turned
on, for instance, we also get:
sd 0:0:0:0: [sda] Send: 0x0fb89180
sd 0:0:0:0: [sda] CDB: Read(16): 88 20 00 00 00 00 00 00 00 20 00 00 00 08 00 00
sd 0:0:0:0: [sda] Done: 0x0fb89180 SUCCESS
The patches need to be applied in order.
