Auto Unload

Auto Unload

All registered modules that include an unload routine are automatically unloaded after last close unless they have been configured not to do so. By default, modules are unloaded five minutes after last close. You can change the default auto-unload delay by using systune to modify the module_unld_delay variable. For more information about systune, see the systune (1M) man page entry. To configure a particular module with a specific auto-unload delay, use the ml command. To configure a module so that it is not auto-unloaded, place an N in the flags filed of its master.d file, if it is registered using lboot; otherwise, use ml to register the module, then use the -t option.
