File 0065-Grow-be-even-more-careful-about-handing-a-0-complete.patch of Package mdadm
From 3ee556f8b6d9aa8c843b9f83e88d90a976259f49 Mon Sep 17 00:00:00 2001 From: NeilBrown <neilb@suse.de> Date: Fri, 15 May 2015 15:11:48 +1000 Subject: [PATCH 092/359] Grow: be even more careful about handing a '0' completed value. References: bsc#1081910 Some old kernels set 'completed' to '0' too soon. But modern kernels don't. And when 'mdadm --stop' freezes and resume the grow, 'completed' goes back to zero briefly, which can confuse this logic. So only think '0' might be wrong from an old kernel when the reshape has gone idle.
