Say an RT scenario; you set up your machine with cgroups. You create a cpuset with is disjoint from the others, you frob around with the cpu cgroup, etc.. So once you're all done, you start your RT app into a cgroup. But oh, fail, now you have to go muck about with ioctl()s to get the cache allocation cruft to work. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
