What documentation are you referring to? The futex man page is a wreck,
and I'm not sure what to do with it since glibc removed the futex()
call. You now have to wrap the syscall manually anyway.

If you are referring to the futex.c file itself, I have been documenting
functions as I modify them. If you found any of those lacking, please
let me know which ones and I'll try to clean them up. If you're
referring to those that remain undocumented, please send a doc patch and
I'll review and help get it upstream. I'd like to see this improved as well.
