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.
