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:
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/]

This is still a very long patch series. Several of the patches can be
combined and can be rearranged. 21 patches don't seem to any specific
order.

Yes. This is a needed change. I didn't make it to this patch yet.

Commented on this patch already. Look into using config file like other
tests.

Why not combine the above two patches. The commit summary doesn't
make sense.

I will review rest of the patches. Try to combine a few patches and
collapse fixes. I would like to see all the fixes first and then
renaming from CQM to CMT.

thanks,
