Subject: [PATCH] Enable all events for initramfs
Date: Tue, 13 Jul 2004 11:16:31 +0000	[thread overview]
Message-ID: <40F3C48F.30905@suse.de> (raw)

[-- Attachment #1: Type: text/plain, Size: 584 bytes --]

Hi all,

currently most driver events are not sent out when using initramfs as 
driver_init() (which triggers the events) is called before init_workqueues.

This patch rearranges the init calls so that the hotplug event queue is 
enabled prior to calling driver_init(), hence we're getting all hotplug 
events again.

Patch is relative to 2.6.7-mm6, but should apply to 2.6.8-rc1 also.

Please apply.

Cheers,

Hannes
