Timing differences look improbable. It's the change from !signal_group_exit(signal) to !sig_kernel_only(signr) and quite frankly, I still don't see the point. The comment seems to be wrong too: If SIGSTOP/SIGKILL originate from a descendant of container-init they are never queued (i.e dropped in sig_ignored() in an earler patch). If SIGSTOP/SIGKILL originate from parent namespace, the signal is queued and container-init processes the signal. since the bug was that the SIGSTOP (from within the same container) was _not_ ignored like the comment says.
