Sigh, you are being disruptive again.

Here you pretend that you didn't read the sane solution that was suggested to you 
just three days ago:

I.e. first apply the safe approach, then, after the dependent changes, clean it up 
by introducing the dangerous change.

The thing is, I'm close to summarily NAK-ing any patches from you to the perf 
subsystem, due to the unacceptably low quality patches combined with obtuse 
passive-aggressive obstruction you are routinely burdening maintainers with.

Btw., I noticed that you routinely don't Cc me to perf patches. Please always Cc: 
me to perf patches (both kernel and tooling patches). I still will not apply them 
directly, only if another perf maintainer signs off on them, but I'd like to have 
a record of all your submissions.

Thanks,

	Ingo
