Jason Evans 96d4120ac0 Avoid NULL check in free() and malloc_usable_size(). ... Generalize isalloc() to handle NULL pointers in such a way that the NULL checking overhead is only paid when introspecting huge allocations (or NULL). This allows free() and malloc_usable_size() to no longer check for NULL. Submitted by Igor Bukanov and Mike Hommey.		2012-04-02 14:50:03 -07:00
