Sorry for the colloquialism, it's not actually the same as a ping. A ping
is for something that had no response. This is more about the patch was
acknowledged but did not go further. "Falling through the cracks" is like
picking a bunch of things up with a bucket that has a crack in it. Some of
those things may "fall through the crack" and not be processed.

Well, it will start causing warnings soon because it wastes memory. But
that will likely begin in 6.18 so we are OK, as long as it gets into
linux-next before the warning trigger does.
