This is essentially the same patch that I sent earlier
today. The earlier patch will apply cleanly. However since
the 'sscanf("-1", "%d", &i)' bug is fixed in lk 2.5.47,
this attachment removes the work around.

lk 2.5.47 does not include the 'modprobe/rmmod' fixes from
Patrick Mansfield sent last week. They apply cleanly to
lk 2.5.47 and with them modprobe/rmmod cycles are stable
with scsi_debug.
