seems to have survived)

As far as long-term kernels goes, from the Android perspective we
strongly prefer to snap up to the most recent released kernel on every
platform/device release. I prefer to be as up to date on bugfixes and
features from mainline as possible and minimize the deltas on our
stack 'o patches as much as possible.

We've been getting more aggressive about merging in the -rc#s and then
rebasing on the final during development (before final stabilization
freeze for a release) in the last year or so, and it seems to work
pretty well.

Not all OEMs or silicon vendors are as comfortable with this approach
and I expect some would welcome a long term tree they can count on to
get critical fixes for, though. Device release teams (even our own,
for lead devices we work on) are notoriously risk-averse (often for
good reasons), and tend to get really nervous when they see the total
change count or diff stat for pulling up to a new kernel release close
to "final rom" for a product.
