KUnit Coverage Rules
212+
~~~~~~~~~~~~~~~~~~~~
213+
214+
KUnit support is gradually added to the DRM framework and helpers. There's no
215+
general requirement for the framework and helpers to have KUnit tests at the
216+
moment. However, patches that are affecting a function or helper already
217+
covered by KUnit tests must provide tests if the change calls for one.
