I ran into a problem where scsi_device_cancel encounters scsi_cmnds that
have request pointers that point to freed memory. In one case, the
command was in SCSI_STATE_FINISHED/SCSI_OWNER_HIGHLEVEL; in another it
was SCSI_STATE_UNUSED/SCSI_OWNER_NOBODY. This is where it happens:

These patches (against a 2.6.9 kernel, Redhat AS 4) for st add a
reference count, and fix a few bugs I hit during testing (administrative
removes and cable pulls with IO in progress).
The primary change is adding a kref to the Scsi_Tape structure, to avoid
