I'd prefer if you used a standard notifier struct (probably raw since we have rdev locking; see include/linux/notifier.h) and the callees sorted out their state there. As it is, it's really complicated to make sure that one request doesn't clobber another -- the current use guarantees that but I'm not sure I want to rely on it going forward. johannes
