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, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
