"Make their own version" makes it sound like we've rewritten it. We haven't. We've applied some patches locally over the last two years based on work we've done for our products. It's not a deep fork. We'd be happy to upstream them if there's interest from other users and maintainers. >> Perhaps by moving the code into the kernel tools dir and finding >> someone who actively wants to maintain it, will enable improved >> upstream activities!? Hmm. If there's a well-defined userspace interface there's little reason to bundle it directly, and I think that's the case here. Chris has been busy with other stuff the last couple of years, is there a lot of mmc-utils code that's out there that hasn't been picked up? -Olof -- 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/
