--2201072851-802137771-1698220721=:3649 Content-Type: text/plain; format=flowed; charset=US-ASCII Hello, is there any documentation for cdevsw methods? I am interested in knowing how d_map_single should be written. Most specifically, I want to know if the driver has a chance to track mmaped allocations on its own (as far as I can see there unmap(2) does not call any of the driver's methods).
