From 6b6112842030309c297a521918d1a2e982426fa3 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Fri, 9 Nov 2018 17:12:33 +1100 Subject: [RHEL7.7 PATCH 02/24] 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.
