    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.
