--- Comment #2 from Torvald Riegel <triegel at redhat dot com> ---
It's a duplicate because it seems to rely on the TPS-specific requirements for
rwlock, which we do not intend to implement.

Furthermore, rwlocks aren't guaranteed to be safe to use in real-time
environments, in contrast to mutex kinds that provide PI.
