Subject: [PATCH v1 0/3] kunit: fix bugs in debugfs logs

Currently, the KUnit debugfs logs have a few issues:
1. The results of parameterized tests don’t show up
2. The order of the lines in the logs is sometimes incorrect
3. There are extra new lines in the logs

This patch series aims to fix these issues.

This is an example of a debugfs log prior to these fixes:

   KTAP version 1

   # Subtest: kunit_status
   1..2
 # kunit_status: pass:2 fail:0 skip:0 total:2
 # Totals: pass:2 fail:0 skip:0 total:2
   ok 1 kunit_status_set_failure_test
   ok 2 kunit_status_mark_skipped_test
 ok 1 kunit_status

Note there is an extra line and a few of the lines are out of order.

This is the same debugfs log after the fixes:

   KTAP version 1
   # Subtest: kunit_status
   1..2
   ok 1 kunit_status_set_failure_test
   ok 2 kunit_status_mark_skipped_test
 # kunit_status: pass:2 fail:0 skip:0 total:2
 # Totals: pass:2 fail:0 skip:0 total:2
 ok 4 kunit_status

This is now equivalent to the regular KTAP output for the kunit_status
test.

Thanks!
