Thanks for this, Jonathan, very interesting.
I wonder if it is worthwhile to continue tracking changes to the kernel after it is released
into the wild? It should (AFAICS) be straightforward to track what patches are needed to what
code, for what reason (security, known exploit, race condition, etc.) and from what source.
That would make pretty interesting reading. And any given kernel has only quite a short life
until the next is ready. For myself I'd like the tracking to be as long-term as possible so as
to see how long a tail exists.
