Cleaning up after tests is implemented separately for individual tests
and called at the end of each test execution. Since these functions are
very similar and a more generalized test framework was introduced a

Hi all,
File folio supports any order and multi-size THP is upstreamed[1], so both

Remplace Landlock-specific TEST_F_FORK() with an improved TEST_F() which
brings four related changes:
Run TEST_F()'s tests in a grandchild process to make it possible to
drop privileges and delegate teardown to the parent.
Compared to TEST_F_FORK(), simplify handling of the test grandchild
proces
This has the effect of creating a new test process for either TEST_F()
or TEST_F_FORK(), which doesn't change tests but will ease potential
backports. See next commit for the TEST_F_FORK() merge into TEST_F().

Hi,
This is a long due cleanup to merge TEST_F_FORK() into TEST_F().
This should simplify Jakub's patches by removing the step counter:
