That is interesting, since they are documented quite differently with no
hint that they are the same:

https://www.kernel.org/doc/man-pages/ ->
https://man7.org/linux/man-pages/man2/getrandom.2.html

But, yet:

https://lore.kernel.org/lkml/531cfcd62151916cc7fbade2ecd0311fbafc02a9.1567126741.git.luto <at> kernel.org/

...would not be the first time a developer changed code without updating
the documentation.
