Longterm kernels are maintained on a voluntary basis, which explains
there is no rule. We had 2.6.16, 2.6.27 and now 2.6.32 which were
initially announced as longterm supported. When Greg announced dropping
2.6.27, I proposed to take it over because I have some uses for it and
I know other people who rely on it. Most likely for very similar reasons
Paul and Andi volunteered to maintain 2.6.34 and 2.6.35 alive.

I agree it would be much easier for everyone if all longterm kernels were
announced early. Still there are a lot of users who can't easily upgrade
for whatever reason and who are happy with someone keeping their kernel
updated. I tend to consider that Greg's kernels are more "official" than
other ones, and if some backporting must be done by patch authors, I think
it should be for these kernels first. Also, .32 is not that far away from
the 3 other longterm kernels, so when a developer writes a .32 backport,
chances are that adaptations will not be too hard for the 3 other ones.

While less probable, I'm still amazed by the number of fixes from -master
that still apply to 2.6.27, and sometimes (but to a less extent) even to
2.4.37 ! The fact that fixes and regressions span that many kernel versions
probably is one of the reasons there is demand for longterm kernels.

Just my 2 cents,
