Please, review. [v4] - Change aligned_uint64_t to size_t to make (some) 32bit hosts happy. Please review. [v3] - Addressed reviews - All counters are now atomic, either Stat64 or atomic. - Rename duplicated to zero_pages - Rename normal to zero_pages. Please review. [v2] - fix typos found by David Edmondson - Add review-by tags. Please review. [v1] On previous series we cerate ram_atomic_counters. But we basically need that all counters are atomic. So move back to only have ram_counters, just with a new type that allows the atomic counters. Once there, move update of stats out of RAM mutex. And make multifd_bytes atomic. Later, Juan.
