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.
v2: - Rebased on top of next to solve the conflicts - Added 2 patches related to resctrl FS mount/umount (fix + cleanup) - Consistently use "alloc" in cache_alloc_size() - CAT test error handling tweaked - Remove a spurious newline change from the CAT patch - Small improvements to changelogs
