Author: delphij Date: Thu Oct 21 20:31:50 2010 New Revision: 214181 URL: http://svn.freebsd.org/changeset/base/214181 Log: Call chainevh callback when we are invoked with neither MOD_LOAD nor MOD_UNLOAD. This makes it possible to add custom hooks for other module events. Return EOPNOTSUPP when there is no callback available.
