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.
