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.
