New Revision: 204807
URL: http://svn.freebsd.org/changeset/base/204807
Log:
Destroy UDP UMA zones (empty or not) upon network stack teardown
to not leak them making the VM subsystem unhappy with every stoped vnet(*).
We will still leak pages (especially as zones are marked NOFREE).
(*) This will also keep vmstat -z more usable.
