Well, that's right.

This material has been in the works for quite a while and it missed
the merge window mostly due to unfavorable timing, so it is not a
last-minute thing.

It is self-contained and it doesn't interfere with the existing
features, so it is not likely to introduce regressions in my view.

I didn't think that there was much to gain by postponing it, because
it wouldn't change substantially between now and the next merge window
and the testing coverage of it in linux-next would be limited.  On the
other hand, having it in the tree would encourage people to build on
top of it, exercise it and provide feedback, so I decided to include
it here.

However, if you'd rather skip it this time, I'll be happy to resend
the pull request without it.
