Modified files:
sys/vm uma_core.c
Log:
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.
