New Revision: 324128
URL: https://svnweb.freebsd.org/changeset/base/324128
Log:
MFC r323786
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.
