Anyone have insight into the origin of this text? It's bothered me for years because I'm pretty much 100% sure it's wrong, but keep wondering if there's some subtlety I missed each time I run across it again.

Tried to figure that out from Git but it's not clear. From newest to oldest changes:
* github.com/mkerrisk/man-p
* github.com/mkerrisk/man-p
* github.com/mkerrisk/man-p
It's problematic that official documentation is scarce. Linux man-pages is an interpretation of that scarce info.
The man-pages project is often out-of-sync with upstream code and the upstream stances on various things. The random(4) and random(7) pages have been major examples. As a current example, the blocking pool was removed and /dev/random blocks until init at boot like getrandom.

The GRND_RANDOM parameter for getrandom is simply a no-op. I don't think there's upstream documentation on the random interfaces aside from the code. For futex, there's actually some upstream documentation. Linux should really have official system call man pages, etc...
