Subject: Re: [RFC PATCH v1] pin_on_cpu: Introduce thread CPU pinning system call

Hello

I would like to note that this does not help userspace to express
dynamic scheduling relationships among processes/threads such as "do
not run processes A and B on the same core" or "run processes A and B
on cores sharing the same L2 cache".

Sincerely
Jan
