For any action initiated from user space you will not hold mmap sem. So you can call the unregister function. Then you need to do a synchronize_rcu before freeing the structures. It is also possible to shut this down outside via f.e. a control thread. The control thread can acquire mmap_sem and then unregister the notifier. Am I missing something? ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
