Christoph, why are you *STILL* arguing??

You caused a *regression* in a userspace ABI plain and simple, and a 
security relevant one. Furtermore you modified kernel/events/core.c yet 
you never even Cc:-ed the parties involved ...

All your excuses, obfuscation and attempts to redefine the universe to 
your liking won't change reality: it worked before, it does not now. Take 
responsibility for your action for christ's sake and move forward towards 
a resolution , okay?

When can we expect a fix from you for the breakage you caused? Or at least 
a word that acknowledges that you broke a user ABI carelessly?

Thanks,

	Ingo
