Dave Miller has done some kernel compiles and I have some benchmarks here that I never posted because they do not show any material change as far as I can see. I will be posting that soon when this is complete (also need to do the same for the atomic page fault ops and the prefaulting patch). > > > Should we be managing the kernel threads with the kthread() API? > > > > What would you like to manage? > > Startup, perhaps binding the threads to their cpus too. That is all already controllable in the same way as the swapper. Each memory node is bound to a set of cpus. This may be controlled by the NUMA node configuration. F.e. for nodes without cpus. - 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/
