This patch set has several miscellaneous fixes to resctrl selftest tool
that are easily visible to user. V1 had fixes to CAT test and CMT test
but they were dropped in V2 because having them here made the patchset
humongous. So, changes to CAT test and CMT test will be posted in another
patchset.
Change Log:
v4:
- Address various comments from Shuah Khan:
1. Combine a few patches e.g. a couple of fixing typos patches into one
and a couple of unmounting patches into one etc.
2. Add config file.
3. Remove "Fixes" tags.
4. Change strcmp() to strncmp().
5. Move the global variable fixing patch to the patch 1 so that the
compilation issue is fixed first.
