Log: Allow rtprio_thread to operate on threads of any process This in particular unbreaks rtkit. The limitation was a leftover of previous state, to quote a comment: /* * Though lwpid is unique, only current process is supported * since there is no efficient way to look up a LWP yet. */ Long since then a global tid hash was introduced to remedy the problem. Permission checks still apply.
