To be honest, I actually did not want to poke at this too much, given that both ppc and sparc seem to have essentially the same logic. But my gut feeling is that if the pool->hint hasn't resulted in a succesful area_alloc, we might as well reset it for the next iommu*range_alloc-er, because it's likely that the next alloc will also need to wrap and search anyway.. --Sowmini -- To unsubscribe from this list: send the line "unsubscribe sparclinux" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
