<pre>I couldn't find a component for libnftnl, so I added the person who did last
couple of releases to CC. Please reassign as needed.
When building libnftl with clang, the following warnings are being output:
ruleset.c:611:1: warning: attribute declaration must precede definition
[-Wignored-attributes]
EXPORT_SYMBOL(nftnl_ruleset_parse_buffer_cb);
This results in libnftnl library without any exported symbols. A similar
problem was found and fixed in libmnl [1]. The patch is the same, and there's
one for version libnftnl-1.0.7 [2] (doesn't apply to git master anymore) which
makes libnftnl build cleanly and makes the required symbols visible again.
