There are a number of atomic_t usages in the kernel where atomic_t api is used strictly for counting sequence numbers and other statistical counters and not for managing object lifetime.
We already have something in Linux called a sequence counter, and it's different from this. ID counter? instance number? monotonic_t? stat_t?
No results for monotonic_t or stat_t. Can you give me a pointer to what your referring to.
We have a seqcount_t. We need to call this something different. maybe we should call it stat_t (and for that usage, stat_add() as well as stat_inc() is a legitimate API to have).
