t think we can use that text. It's from the
Solaris man page as far as I can tell, and I doubt that it's
under a license that we can use.
If that's the case, we need to go back and come up with an
original text. It might draw inspiration from the Solaris page,
and take actual text
arts on another topic, and doesn't
see linux-man@). I'll respond to that patch soon. (There are some problems
that mean I could not accept it, AFAICT.)

excellent new flags have been overloaded into this one system call.
Some of those certainly violated the "does not change the semantics
of the application" statement, but, sadly, the kernel developers who
implemented MADV_REMOVE or MADV_DONTFORK did not think to send a
patch

Thanks for reviewing the pages! I'll trim everything that we agree

This patch fixes two separate buglets in calls to futex_lock_pi():
* Eliminate unused 'detect' argument
* Change unused 'timeout' argument of FUTEX_TRYLOCK_PI to NULL
The 'detect' argument of futex_lock_pi() seems never to have been
used

Well, regardless of what it technically means, there's always going
to be scope for ambiguity, and that's where we differ from computers:
we can ask ourselves the question: will other human beings interested
in the API/ABI care about
