Author: alc Date: Sat Sep 30 18:32:00 2017 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.
