Comment # 1 on bug 1100734 from Takashi Iwai

Grrr, CONFIG_RT_GROUP_SCHED was enabled again on Leap 15.0.  It was overseen.

Now I disabled it and pushed to openSUSE-15.0 branch.
Could you check later the kernel in IBS Devel:Kernel:openSUSE-15.0 repo?
   http://dist.suse.de/ibs/Devel:/Kernel:/openSUSE-15.0/standard/

The git branch will be synced to OBS once per day, and the fix will be
available in OBS Kernel:openSUSE-15.0 repo in tomorrow, too.
