Author: emaste Date: Fri Apr 22 21:38:37 2016 New Revision: 298493 URL: https://svnweb.freebsd.org/changeset/base/298493 Log: MFC r277205 (imp): Reserve and ignore the a new module metadata type MDT_PNP_INFO for associating an optional PNP hint table with this module. In the future, when these are added, these changes will silently ignore the new type they would otherwise warn about. It will always be safe to ignore this data. Get this into the builds today for some future proofing.
