Fedora kernel folks don't really pay attention to utrace innards except to
make sure that I get the flames about them. The place dedicated to
discussion of those innards is <utrace-devel(a)redhat.com>. (It's fine to
mention the Fedora kernel versions and bugzilla links on that list.)
That fix is one that I just did last week, in fact. I didn't get around to
the commit and push before the (USA) long holiday weekend. I've fixed some
of the outstanding Fedora ptrace issues (now all represented in the
ptrace-tests suite), but still had an intermittent problem to track down.
Even with it still not perfect, I'll do the push today and post on
utrace-devel about the unresolved details.
Thanks,
Roland
