Subject: [PATCH 00/27] ext4: add lots of KUnit tests!
Date: Wed, 11 Nov 2026 23:06:11 -0500 [thread overview]
Message-ID: <20261112040638.1576836-1-tytso@mit.edu> (raw)
These unit tests were written using the writing-kunit-tests.md
prompt[1], and then lightly reviewed by a human with only a few
fix-ups needed.

While the LLM was busily generating these unit tests, it also found
around two dozen potential bug fixes[2]. Those will be sent in a
separate series.

Hopefully extending ext4's Kunit coverage will make it easier to
sanity check the flood of AI generated patch submissions. IOW, since
these tests were created Gemeni Pro, I'm hoping that we can use fire
to fight fire. :-)
So as I process the AI slop backlog, my plan is to do trial merges to
determine whether the patches break the unit tests or not. Which to
be fair, might be an indication of breakage of the unit tests, and not
necessarily a bug in the patches under review.
The patches in this series are available at the ext4.git tree on the
branch ext4-kunit-tests[3]. The patch series was originally based on
v7.3-rc4, so you want to try merging with with v7.4-rc2 or later, use
the branch ext4-kinit-tests-merge[4].
