Hi Ilpo,

A few places currently lack umounting resctrl FS on error paths:
- cmt_resctrl_val() has multiple error paths with direct return.
- cat_perf_miss_val() has multiple error paths with direct return.
In addition, validate_resctrl_feature_request() is called by run_mbm_test() and run_mba_test(). Neither MBA nor MBM test tries to umount resctrl FS.
Each and every test does require resctrl FS to be present already for feature check. Thus, it makes sense to just mount it on higher level in resctrl_tests.c and properly pair it with umount.
Move resctrl FS (re)mount/unmount into each test function in resctrl_tests.c. Make feature validation to simply check that resctrl FS is mounted.
Fixes: 91db4fd9019a ("selftests/resctrl: Remove duplicate codes that clear each test result file")
Could you please elaborate how this commit is the culprit?
