Even if CONFIG_NO_HZ is new this is a an important regression, and yes we should avoid regressions wherever we can, and for such a quite important feature we should fix it. On the other hand blktrace is using the wrong interface, and it has been told multiple times on lkml that sched_clock() should never ever be used outside the scheduler. So the burden to fix this regression lies on the shoulders of the blktrace maintainer. No need for silly name calling here. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
