Re: [RFC][PATCH 2/7] UBC: core (structures, API)

+struct user_beancounter
+ atomic_t ub_refcount;

Why not use a struct kref here instead of rolling your own reference
counting logic?

We need more complex decrement/locking scheme than krefs
provide. e.g. in __put_beancounter() we need
atomic_dec_and_lock_irqsave() semantics for performance optimizations.
