Something like this? commit 1ffaa640c6ba135aafc91841204e41846eae6841 Author: Hendrik Brueckner <[email protected]> Date: Mon Mar 8 12:26:26 2010 +0100 [S390] smsgiucv_app: deliver z/VM CP special messages (SMSG) as uevents The smsgiucv_app driver registers a callback with the smsgiucv driver to receive z/VM CP special messages (SMSG) starting with "APP". When the callback is called for special messages, the driver creates an uevent for the received message. The uevent consists of additional environment data containing the message prefix ("APP"), message sender, and message content. udev rules can be used to trigger application specific actions through matching the content or sender of the special message.
