It's strange that [1/3] doesn't have cc:stable, but [2/3] and [3/3] do
not.  What is the thinking here?

I expect we'd be OK with merging these into 5.16-rc1.  This still gives
another couple of months in -rc to shake out any problems.  But I
suspect the -stable maintainers will merge and release the patches
before they are released in 5.16.

In which case an alternative would be not to mark these patches
cc:stable and to somehow remember to ask the -stable maintainers to
merge them after 5.16 has been on the streets for a suitable period.

Greg, thoughts?
