Author: alc Date: Wed Sep 20 04:59:52 2017 New Revision: 323786 URL: https://svnweb.freebsd.org/changeset/base/323786 Log: In r288122, we changed vm_page_unwire() so that it returns a Boolean indicating whether the page's wire count transitioned to zero. Use that return value in zbuf_page_free() rather than checking the wire count.
