Re: [patch] add private data to notifier_block

struct notifier_block *next;
+ void *data;
int priority;
};

Well, it might introduce warnings in users who weren't using named
initializers -- their bare priority initialization might now shift to
trying to initialize a pointer.

Though, that's probably a good thing as it gives an opportunity to
convert them. We also don't want to create a padded structure by
putting the void * after the int.
