But yeah, we haven't been replacing it > with anything very useful. it's very easy to explain it now that you spontanously used that concept in 2.6: classzone is the piece of ram represented by what you previously called alloc_type in 2.6.9 mainline alloc_pages function. You wrote that code so you know what it means. If you prefer to still call that alloc_type that's fine with me. - 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/
