Hi Ming,

I agree that the patch in my previous email won't address potential calls of
.release functions while a module is being unloaded or after a module has been
unloaded. However, that's not the purpose of that patch. The purpose of that
patch is to rework all code that modifies members of the scsi host template.

Thanks,

Bart.
