--- Comment #25 from Mark Johnston <markj at FreeBSD.org> ---
I see another problem in arc_available_memory(): we're using
vmem_size(kernel_arena, VMEM_FREE) to determine whether to reap memory. It used
to be vmem_size(kmem_arena), and kmem_arena was initialized with vm_kmem_size
bytes. But kernel_arena is grown on demand, so it's now bogus to use the
arena's size to determine whether to reclaim memory.
