The changelog appears to spell this all out quite well?  Unusually
well, in my experience ;)

A couple of things...

- We'll be looking for a manpage update please.  (Search MAINTAINERS
  for "manpage")

- As it's a linux-specific feature, a test under
  tools/testing/selftests would be appropriate.  I don't know how much
  that work will be.  Do we have other linux-specific signal extensions
  which could piggyback onto that?
