ext4: add .kunitconfig fragment to enable ext4-specific tests
As of [1], we no longer want EXT4_KUNIT_TESTS and others to `select`
their deps. This means it can get harder to get all the right thing
ext4: add .kunitconfig fragment to enable ext4-specific tests
As of [1], we no longer want EXT4_KUNIT_TESTS and others to `select`
their deps. This means it can get harder to get all the right things
selected as we gain more tests w/ more deps over time.
This patch (and [2]) proposes we store kunitconfig fragments in-tree to
represent sets of tests. (N.B. right now we only have one ext4 test).
There's still a discussion to be had about how to have a hierarchy of
these files (e.g. if one wanted to test all of fs/, not just fs/ext4).
But this fragment would likely be a leaf node and isn't blocked on
deciding if we want `import` statements and the like.
Usage
=====
Before [2] (on its way to being merged):
$ cp fs/ext4/.kunitconfig .kunit/
$ ./tools/testing/kunit/kunit.py run
After [2]:
$ ./tools/testing/kunit/kunit.py run --kunitconfig=fs/ext4/.kunitconfig
".kunitconfig" vs "kunitconfig"
===============================
See also: commit 14ee5cfd4512 ("kunit: Rename 'kunitconfig' to '.kunitconfig'").
* The bit about .gitignore exluding it by default is now a con, however.
* But there are a lot of directories with files that begin with "k" and
so this could cause some annoyance w/ tab completion*
* This is the name kunit.py expects right now, so some people are used
to .kunitconfig over "kunitconfig"

* 372/5556 directories isn't too much, but still not a small number:
$ find -type f -name 'k*' | xargs dirname | sort -u | wc -l
372
