not really. Either use the #include, or if you want less stuff included, 
split notifier.h into notifier_types.h and notifier.h and move the data 
structure declarations to notifier_types.h and then #include 
notifier_types.h. (spinlock_types.h works like this.) This allows 
headers to be separated into pure 'data structure' and 'access methods' 
portions. Using explicit forward declarations is less cleaner.
