    systemd: fix formatting IDE storage does not trigger "change" uevents
    
    Formatting IDE storage does not trigger "change" uevents. As a result
    clients using udev API don't get any updates afterwards and get outdated
    information about the device.

+clients using udev API don't get any updates afterwards and get outdated
+information about the device.

+
+Upstream-Status: Denied
+
+qemu by default emulates IDE and the linux-yocto kernel(s) use
+CONFIG_IDE instead of the more modern libsata, so disks appear as
+/dev/hd*. A similar patch rejected by upstream because CONFIG_IDE
+is deprecated.
