Personally I like the idea.

Backporting features to such old kernels gets more and more painful and
sometimes even not feasible at all.
For example, we will never be able to run batman v on old kernels for
this reason.

Another point is that every now and then we get bugs from people trying to =
use
batman-adv on ancient kernels and spending time on those bugs can be really=
 time
consuming..that's why often the solution is "upgrade your kernel". :)

Unless there is somebody who wants to commit on maintaining such old kernel=
s,
I'd agree with Sven in limiting our support to kernels >=3D 3.2.


Cheers,
