The patch changes the behaviour of the interface between the Linux
kernel and userspace core dump handlers. The previous behaviour was
unlikely to be depended on by any core dump handler but it is still a
behaviour change, so I think it would be best to keep it out of the
stable branches and would prefer to have folks encounter the change as
Linux distros etc roll out 5.3 and later into their dev releases.

We discussed this on #kernelnewbies a while ago and gregkh agreed that
it should stew a while longer before reaching any stable releases.

In addition if it gets backported to stable releases, my patch for
core(5) from man-pages will have to get more complicated :)
