Two different > things. 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 -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
