  Log:
  Merge uma_core.c:1.128 from HEAD to RELENG_6:
  
    Further UMA statistics related changes:
  
      - Add a new uma_zfree_internal() flag, ZFREE_STATFREE, which causes it to
        to update the zone's uz_frees statistic.  Previously, the statistic was
        updated unconditionally.
  
      - Use the flag in situations where a "real" free occurs: i.e., one where
        the caller is freeing an allocated item, to be differentiated from
        situations where uma_zfree_internal() is used to tear down the item
        during slab teardown in order to invoke its fini() method.  Also use
        the flag when UMA is freeing its internal objects.
  
      - When exchanging a bucket with the zone from the per-CPU cache when
        freeing an item, flush cache statistics back to the zone (since the
        zone lock and critical section are both held) to match the allocation
        case.
