Hi Randy,

It was applied, as bc67f1c454fb ("docs: futex: Fix kernel-doc
references") in 5.16-rc1. But 5.10.y and 5.15.y picked up from the
refactoring only 77e52ae35463 ("futex: Move to kernel/futex/"). 

So this change is a specific backport of subset of it, to 5.10.y and
5.15.y thus the commit message:

Here pointing out explicitly that there is no (direct) upstream commit
for it. 

Hope this helps,
