Subject: [RHEL7.7 PATCH 02/21] Document PART-POLICY lines
|
|
|
c8f3db |
|
|
|
c8f3db |
PART-POLICY has been accepted in mdadm.conf since the same
|
|
|
c8f3db |
time that POLICY was accepted, but it was never documented.
|
|
|
c8f3db |
So add the missing documentation.
|
|
|
c8f3db |
|
|
|
c8f3db |
Also fix a bug which would have stopped it from working if
|
|
|
c8f3db |
anyone had ever tried to use it.
