[PATCH v6 0/6] Fix nits in the kunit

[PATCH v6 0/6] Fix nits in the kunit

[SeongJae Park]

This patchset contains trivial fixes for the kunit documentations and
the wrapper python scripts.


Baseline
--------

This patchset is based on 'kselftest/fixes' branch of
linux-kselftest[1].  A complete tree is available at my repo:
https://github.com/sjp38/linux/tree/kunit_fix/20191205_v6


Version History
---------------

Changes from v5
(https://lore.kernel.org/linux-kselftest/20191205093440.21824-1-sjpark@amazon.com):

 - Fix the 4th patch, "kunit: Place 'test.log' under the 'build_dir'" to

 - Remove "docs/kunit/start: Skip wrapper run command" (A similar
   approach is ongoing)
 - Make 'build_dir' if not exists

SeongJae Park (6):
  docs/kunit/start: Use in-tree 'kunit_defconfig'

[PATCH v6 1/6] docs/kunit/start: Use in-tree 'kunit_defconfig'

[SeongJae Park]

The kunit doc suggests users to get the default `kunitconfig` from an
external git tree.  However, the file is already located under the
`arch/um/configs/` of the kernel tree.  Because the local file is easier
to access and maintain, this commit updates the doc to use it.

[PATCH v6 2/6] kunit: Remove duplicated defconfig creation

[SeongJae Park]

'--defconfig' option is handled by the 'main() of the 'kunit.py' but
again handled in following 'run_tests()'.  This commit removes this
duplicated handling of the option in the 'run_tests()'.

[PATCH v6 3/6] kunit: Create default config in '--build_dir'

[SeongJae Park]

If both '--build_dir' and '--defconfig' are given, the handling of
'--defconfig' ignores '--build_dir' option.  This commit modifies the
behavior to respect '--build_dir' option.

[PATCH v6 4/6] kunit: Place 'test.log' under the 'build_dir'

[SeongJae Park]

'kunit' writes the 'test.log' under the kernel source directory even
though a 'build_dir' option is given.  As users who use the option might
expect the outputs to be placed under the specified directory, this
commit modifies the logic to write the log file under the 'build_dir'.

[PATCH v6 5/6] kunit: Rename 'kunitconfig' to '.kunitconfig'

[SeongJae Park]

This commit renames 'kunitconfig' to '.kunitconfig' so that it can be
automatically ignored by git and do not disturb people who want to type
'kernel/' by pressing only the 'k' and then 'tab' key.

I tried to reproduce the warning on my side using 'git am' and 'checkpatch.pl',
but those doesn't show me such warnings.  Could you please let me know what

Park <sjpark@amazon.de>'.

Seems like 'send-email' has ignored 'From:' in my original patche files.  I
