Sure but you keep old ones around once its stable. This is a completely pointless conversation to have before 2.6.0-test kernels. There isnt a stable in kernel dvb api yet because its not been shipped in a stable kernel. (Although I'd note the api has been as stable if not more stable than some in kernel stuff 8)) - 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/
