That brings up an interesting point. Among those distributions who are shipping a kernel based on 2.6.32 mainline how big of a delta are they from each other and from mainline? Are the differences between vendor kernels which are ostensibly the same versions as large as the differences between sequential mainline versions? And for the long lived releases.. how large do those deltas after a year or two?

Shuttleworth's misplaced example of cadence

my understanding is that the distros are down to a 'couple hundred' patches to the baseline kernel. This is an order of magnitude or two fewer changes than between kernel versions (and generally much smaller changes)

the question about long-lived kernels is interesting, but I suspect it's still smaller than between mainline kernel releases.

Also remember that the patches are all available, so the distros can and do see what each other are doing (and there is cross pollination between the kernel teams in some cases) so I suspect the differences are smaller than just counting the patches of each distro and summing them up.
