From e6ffbcb6cd0ac471223df24ae77eb486c1ee68cc Mon Sep 17 00:00:00 2001 From: Adrian Drzewiecki Date: Wed, 18 Aug 2010 11:49:02 +1000 Subject: md: Notify sysfs when RAID1/5/10 disk is In_sync. When RAID1 is done syncing disks, it'll update the state of synced rdevs to In_sync. But it neglected to notify sysfs that the attribute changed. So any programs that are waiting for an rdev's state to change will not be woken.
