File 0070-81cio_ignore-rewrite-module.patch of Package dracut.376
From 137090516e1c48ef134209c2ed4f625799691090 Mon Sep 17 00:00:00 2001 From: Hannes Reinecke <hare@suse.de> Date: Tue, 17 Jun 2014 16:45:06 +0200 Subject: 81cio_ignore: rewrite module Rewrite cio_ignore module to rely on the dracut commandline parameter 'rd.cio_accept', which takes a comma-separated list of CCW IDs. Each of those IDs are being removed from the list of devices from cio_ignore. The default values for rd.cio_accept are taken from /boot/zipl/active_devices.txt.
