Subject: [PATCH 0/5] selftests/resctrl: Fixes to failing tests

Fix three issues with resctrl selftests.

The signal handling fix became necessary after the mount/umount fixes.

The other two came up when I ran resctrl selftests across the server
fleet in our lab to validate the upcoming CAT test rewrite (the rewrite
is not part of this series).

These are developed and should apply cleanly at least on top the
benchmark cleanup series (might apply cleanly also w/o the benchmark
series, I didn't test).

Ilpo Järvinen (5):
  selftests/resctrl: Extend signal handler coverage to unmount on
    receiving signal
  selftests/resctrl: Remove duplicate feature check from CMT test
  selftests/resctrl: Refactor feature check to use resource and feature
    name
  selftests/resctrl: Fix feature checks
  selftests/resctrl: Reduce failures due to outliers in MBA/MBM tests
