Consider the following scenario. Let a high priority task H wait on a priority inheritance mutex M owned by a low priority task L. Restart task H. This should remove the priority inherited by H from L. This is currently not the case and the patch set fixes this.
A test for this is in the new validation test suite which will be sent for review later.
