Guess why? What comes around goes around.

You just dismissed (without apparently even understanding them) my
concerns about a patch that comes out of the blue, when I ask whether you
really looked into trying to do it other ways.

You didn't even post the code that would _use_ this. You just blindly
claim that you're the only one who can know things like this and can do
serialization, and that your way is the only approach.

Color me not impressed.

I did not insult you until you didn't even understand my first email. We
have had an efficient 32-bit rwlock in the kernel for a long time. So I
(quite naturally) questioned your statement (that had no backing up
what-so-ever) that it cannot be done.

Sure, futex use and user space is not the same as the kernel code. It's
possible that you really do need 64-bit futexes. But quite frankly, the
only thing you have proven so far is that you're an ass.
