How do you know that for all tools out there? I know, I know, moving them to /sys/.../machinecheck/ is the right thing to do but they're exposed to userspace and we're breaking it with this patch. And we don't break userspace so I'd guess we're stuck with the current situation. Sorry. -- Regards/Gruss, Boris.
