Equally note that if you change find_new_ilb() to not pick the very first cpu in the mask you already get the bouncy bounce, because this routine will in fact try and move things to the first cpu first. So if you go change find_new_ilb() you should also amend the iteration order here. -- 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/
