counting scsi hosts
Hi,
when unloading and reloading SCSI modules, the number of SCSI hosts is
increased like this:

At some time, a limit (like 32?) might prevent me from reloading the
modules and force me to reboot.
Is it normal that the kernel (2.6.9 SMP) or the modules seems to think
that the number of SCSI hosts is increasing though they aren't? Is there
a way to reuse host numbers that have been used previously?
