Subject: [RHEL7.7 PATCH 02/21] 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. |
