From 526647320e696f434647f38421a6ecf65b859c43 Mon Sep 17 00:00:00 2001 From: Neil Brown <neilb@notabene.brown> Date: Sat, 28 Jun 2008 08:31:44 +1000 Subject: Make sure all changes to md/dev-XX/state are notified The important state change happens during an interrupt in md_error. So just set a flag there and call sysfs_notify later in process context.
