+Subject: Get required multipath wwids from sysfs
+References: bnc#883883
+Patch-mainline: v0.8.16
+Git-commit: 4aa46801a53070dc0b0c27f4247cdc8e2b678694
+
+The dracut code path must use for_each_host_dev_and_slaves_all to
+find multipath devices that are "hidden" beneath e.g. an LVM volume.
+That will iterate over all devices in the chain down to each physical
+device. Note that /lib/udev/scsi_id sends a low-level SCSI command to
+the device to find out the WWID. If it sends it to an unreachable
+device in an active-passive multipath setup, it may hang indefinitely.
+
+But the WWID is already available as the name of the multipath device,
+so we can get it from the kernel via sysfs.
