"eventual" hints that this submission was not intended?

"this tree" referred to by first sentence?
I peeked at the first test and it seems to rely on features that do not
exist in upstream resctrl, for example an info file named "schema_format".
Considering all this I do not see this as a valid upstream submission.
These tests do seem useful though. When they are ready, please submit
against "next" branch of
https://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest.git
Thank you.
