Here is a series with some fixes and cleanups to resctrl selftests and rewrite of CAT test into something that really tests CAT working or not condition.
I know that this series will conflict with some of patches from Shaopeng Tan that so far have not made it into the kselftest tree. Due to CAT test rewrite done in this series, some of those patches would no longer be relevant anyway but some of them are still very valid (I've not tried to reinvent the fixes in Shaopeng's series in this series).
