I agree
Looking at Jack's improvement list, they don't exactly scream "major version" to me. Wake on WLAN? Yeah, that's worth revving the big number over...
I think maybe Jack should have read the full quote from Torvalds. They revved the major because they felt it was time to rev the major, that's IT. If it signals anything else to anyone else, that's their own fault for not doing any kind of research. No one who would go within 10 feet of a Linux box cares if the kernel is at 2.X or 3.X, because the distro version is so much more important anyways.
