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" [1] https://lore.kernel.org/linux-ext4/20210122110234.2825685-1-geert@linux-m68k.org/ [2] https://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest.git/commit/?h=kunit&id=243180f5924ed27ea417db39feb7f9691777688e * 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 Signed-off-by: Daniel Latypov <dlatypov@google.com> Link: https://lore.kernel.org/r/20210210013206.136227-1-dlatypov@google.com Signed-off-by: Theodore Ts'o <tytso@mit.edu> 2021-02-10 09:32:06 +08:00			`CONFIG_KUNIT=y`
