As I posted to the linux-kernel mailing list, the 3.4 kernel tree will be the next long-term kernel that I will be maintaining for at least 2 years.
Currently I'm maintaining the following stable kernel trees for the following amount of time:
- 3.0 - for at least one more year
- 3.4 - for at least two years
- 3.5 - until 3.6.1 is out
