I would like that sort of outcome, at least assuming we are not > hammering any of the architectures. I would go with the local_inc approach, and even add a srcu_read_un/lock_nmi() that does that if you want. Probably should add lockdep to detect if the _nmi calls is ever used along with non _nmi calls and complain about that. But this will be something for the next merge window, not the one coming up. -- Steve
