I don't see how this would work.  If I add unit tests to ext4, they
would be in fs/ext4.  And to the extent that I need to add test mocks
to allow the unit tests to work, they will involve changes to existing
files in fs/ext4.  I can't put them in the ext4.git tree without
pulling in the kunit changes into the ext4 git tree.  And if they ext4
unit tests land in the kunit tree, it would be a receipe for large
numbers of merge conflicts.
