Subject: [PATCH v4 00/17] Miscellaneous fixes for resctrl selftests

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.

Please note:
- I didn't move the patch of renaming CQM to CMT to the end of the series
  because code and commit messages in a few other patches depend on the
  new term of "CMT". If move the renaming patch to the end, the previous
  patches use the old "CQM" term and code which will be changed soon at
  the end of series and will cause more code and explanations.
[v3: https://lkml.org/lkml/2020/10/28/137]

v3:
Address various comments (commit messages, return value on test failure,
print failure info on test failure etc) from Reinette and Tony.
[v2: https://lore.kernel.org/linux-kselftest/cover.1589835155.git.sai.praneeth.prakhya@intel.com/]

v2:
1. Dropped changes to CAT test and CMT test as they will be posted in a later
   series.
2. Added several other fixes
[v1: https://lore.kernel.org/linux-kselftest/cover.1583657204.git.sai.praneeth.prakhya@intel.com/]
