I think that would be better. I don't think we'll do the next elfutils
release before glibc 2.20 is released. But if we do, it would be
somewhat inconvenient if we relied on an unreleased glibc version.
I'll probably remember because I see the patch is in fedora rawhide now
and when releasing I make sure all fedora distro patches have been
properly upstreamed. But if you could remind me when glibc 2.20 is
released that would be appreciated.
