+ ZFS users on amd64 machines with 4GB or more of RAM should
+ reevaluate their need for setting vm.kmem_size_max and
+ vm.kmem_size manually. In fact, after recent changes to the
+ kernel, the default value of vm.kmem_size is larger than the
+ suggested manual setting in most ZFS/FreeBSD tuning guides.
