Author: rstone Date: Fri May 25 23:24:16 2012 New Revision: 236030 URL: http://svn.freebsd.org/changeset/base/236030 Log: MFC r227342 The in-kernel CTF parser caches the result of its first attempt to parse CTF data from a module. On subsequent attempts to retrieve CTF data for a module, return an error if there no CTF data. This fixes a panic if you try to enable fbt probes on a module without CTF data twice.
