That's not a valid argument. That's an _excuse_.
Guys, binary compatibility is important. It's important enough that if
something got extensively used on development kernels, it's _still_ a hell
of a lot more important than most other things around. The _only_ things
that trump binary compatibility are
- developer sanity (ie it has to be truly mindbogglingly hard to support
the old interface)
- stability (ie if the old interface was so badly designed that it can't
be done right - mmap on /proc/<pid>/mem was one of these).
- it's been deprecated over at least one full stable release.
Something like "it's only been in the development kernels" is simply not
an issue. The only thing that matters is whether it is used by various
binaries or not. And I think futexes are used a lot by glibc..
