Are we talking about the same thing at all?

We're talking about the *COMPAT* vdso, right?

The one you were just told Fedora had never _ever_ enabled? And you
are seriously arguing that "peformance" is relevant, while at the same
time trying to claim that the fact that it DOES NOT WORK on SuSE -
which *did* enable it - is not such a big deal, and that we should
ignore the "don't break user space" rule?

Seriously?

WTF?
