As part of the Distribution
Kernels microconference at Linux Plumbers Conference 2019, Matthias
Männich described how the Android project monitors changes to the internal
kernel ABI. As Android kernels evolve, typically by adding features and
bug fixes from more recent kernel versions, the project wants to ensure
that the ABI remains the same so that out-of-tree modules will still
function. While the talk was somewhat Android-specific, the techniques and
tools used could be applied to other distributions with similar needs
(e.g. enterprise distributions).
