From b62b75905d571c29262a6c38cf9e5f089c203871 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Tue, 21 Oct 2008 13:25:21 +1100 Subject: md: use sysfs_notify_dirent to notify changes to md/array_state Now that we have sysfs_notify_dirent, use it to notify changes to md/array_state. As sysfs_notify_dirent can be called in atomic context, we can remove the delayed notify and the MD_NOTIFY_ARRAY_STATE flag.
