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: v5: - Address various comments from Shuah Khan: 1. Move a few fixing patches before cleaning patches. 2. Call kselftest APIs to log test results instead of printf(). 3. Add .gitignore to ignore resctrl_tests. 4. Share show_cache_info() in CAT and CMT tests. 5. Define long_mask, cbm_mask, count_of_bits etc as static variables. 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.
