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.
