- Subject: [PATCH 02/11] Document PART-POLICY lines
- PART-POLICY has been accepted in mdadm.conf since the same
- time that POLICY was accepted, but it was never documented.
- So add the missing documentation.
- Also fix a bug which would have stopped it from working if
- anyone had ever tried to use it.
