Of course, supporting kernel releases over a longer period is a good
thing. However, it takes resources to do this job, to backport fixes or
even features from latest I-pipe versions and to resolve patch conflicts
over older kernels. If you are willing to support our community, you are
always welcome!

How this new (actually it is not that new) longterm strategy of the
Linux kernel will influence I-pipe tip development is not yet well
predictable. Right now I would say the need for certain features only
available in newer kernels will continue to drive updates of I-pipe, not
that some kernel is declared longterm stable. But this also depends on
when the longterm tags will be announced, ahead of releases or much later.
