It works like this: Each buffer header contains a usage counter, which is incremented (up to a -small limit value) whenever the buffer is unpinned. (This requires only the -buffer header spinlock, which would have to be taken anyway to decrement the +small limit value) whenever the buffer is pinned. (This requires only the +buffer header spinlock, which would have to be taken anyway to increment the buffer reference count, so it's nearly free.)
