I think it works the same way for any other SCSI driver and it's
pretty convenient during development. You can unload any network
driver module while the network is still up too. Module reference
count doesn't have any specific meaning of 'use' preassigned other
than it's there to prevent unloading module while the code and data
are being actively used by the processor. It's unfortunate that the
way module reference count is used for libata is causing discomfort to
you but I need much better reason to change it.
Thanks.
