From 71d68ff62f945254240575cd836f5f2a09ced5d2 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Wed, 31 Jul 2013 09:18:57 +1000 Subject: [PATCH] Fix is_resync_complete for RAID10 For RAID10, 'sync' numbers go up to the array size rather than the component size. is_resync_complete() needs to allow for this.
