Here is a series with some fixes and cleanups to resctrl selftests. In v3, the rewritten CAT test is not included as an issue was discovered in one of its components requiring further work before it can be included to mainline.
v3: - Don't include rewritten CAT test into this series! - Tweak wildcard style in Makefile - Fix many changelog typos, remove some wrong claims, and generally improve them. - Add fix to PARENT_EXIT() to unmount resctrl FS - Add unmounting resctrl FS before starting any tests - Add fix for buf leak - Add fix for perf fd closing - Split mount/remount/umount patches differently - Use size_t and %zu for span - Keep MBM print as MB, only internally use span in bytes - Drop start_buf global from fill_buf
v2 (was sent with CAT test rewrite which is no longer included in v3): - 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
