Hi I'm looking at some kobject problem in device mapper and I came across this problem: According to kobject interface specification, If we embed a kobject into the device structure, we shouldn't free the device structure when the device is unloaded, but we should register a "release" callback in kobj_type that will actually free the device structure. What happens in this scenario?: 1) someone references a device kobject 2) the device is unloaded (but the device structure is still in memory because of that reference) 3) the driver module is unloaded 4) the reference obtained at point 1) is dropped, kobject reference count reaches zero and the release callback is called. But that callback points to an unloaded module and causes a crash. How is it solved? Am I missing something?
