sys/cam cam_xpt.c
Log:
Correct an off-by-one in the calculation of the inquiry buffer length
to request from devices during the "long inquiry" portion of our probe.
This same bug was fixed in the 4.x stream a few years ago, but the fix
was never propogated to -current.
This fix is slightly different than in -stable:
o Use offsetof() instead of a hard coded constant so as the make
the code more self-explainatory.
o Round odd long inquiry lengths up so as to avoid tickling ignore
wide residue bugs in broken parallel SCSI devices running with a
wide transfer negotiation.
