[PATCH v7 0/2] selftests: tmpfs: Add kselftest support

[Shivam Chaudhary <cvam0000@gmail.com>]

This version 7 patch series replace direct error handling methods with ksft
macros, which provide better reporting.Currently, when the tmpfs test runs,
it does not display any output if it passes,and if it fails
(particularly when not run as root),it simply exits without any warning or
message.

This series of patch adds:

1. Add 'ksft_print_header()' and 'ksft_set_plan()'
   to structure test outputs more effectively.

2. skip if not run as root.

3. Replace direct error handling with 'ksft_test_result_*',
   macros for better reporting.

v6->v7:
         - Improve the handling of failure macros.

         - Add appropriate use of ksft_exit_fail_msg.

         - Split patch into smaller patches to make it easy to review.

         or failure could be due to not unsupported APIs with appropriate warnings.
