If workable, is such an effort before it's time relative to your TODO? I see that you have an old port to a FC7-based 2.6.21 here: http://people.redhat.com/riel/vmsplit/ Also, do you have a public git repo that you regularly publish to for this patchset? If not a git repo do you put the raw patchset on some http/ftp server? thanks, Mike -- 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/
