This patch has no effect. Indeed, the three patches changing do_signal_stop() have no immediate material effect. They all just clean up the code and prepare the hooks that utrace (or something like it) needs to make tracing stops mesh well with job control stops. I'd thought it might be simpler for review to just roll these three together and send you a single patch to replace signals-tracehook_notify_jctl-change.patch; but Oleg decided to keep it sliced smaller. Thanks, Roland
