Well, then we should go for the minimalist approach and just add a hook to VFS. Multiple different ioctl()s are definitely a bad idea. An frevoke() looks much easier to do than one based on paths. If I understand the issue behind the proposal correctly the caller has opened the device. Regards Oliver
