Comment # 5 on bug 1137686 from Hannes Reinecke

We could enable it for SLE12 SP5, however, I would prefer having an ECO to
change it in SLE15 SP1, too.
>From the technical side there shouldn't be much of an issue, and in anyway it
will only affect us on systems with a large number of LUNs. Typical
installations with only a handful of devices probably won't be seeing a
difference.
But it's precisely those large machines where this change will be visible, and
seeing that we're had had quite some issues already during booting on those
machines I'm a tad reluctant to change it just because we feel like it.
