Subject: [md PATCH 05/13] md/raid5: use sysfs_notify_dirent_safe to avoid NULL pointer
Date: Wed, 12 Jan 2011 09:12:46 +1100 [thread overview]
Message-ID: <20110111221246.12732.4023.stgit@notabene.brown> (raw)
In-Reply-To: <20110111221050.12732.31647.stgit@notabene.brown>
From: Jonathan Brassow <jbrassow@redhat.com>
With the module parameter 'start_dirty_degraded' set,
raid5_spare_active() previously called sysfs_notify_dirent() with a NULL
argument (rdev->sysfs_state) when a rebuild finished.
