Do I need to code for MOD_UNLOAD for driver module that also creates a cdev? I see in the current code that one strategy is to simply call destroy_dev(). I guess detach routines are called automatically and destroy_dev can be done there as well.. Is it reasonable to refuse unload if cdev is in use (in MOD_QUIESCE)? How to check for that best? -- Andriy Gapon
