The document discusses automated backporting of Linux drivers through the use of semantic patches and regular patches. It allows drivers to be backported to previous kernel versions to ensure compatibility. Semantic patches are designed for collateral evolutions and allow drivers to be patched for previous kernels through tools like Coccinelle to enable automated backporting as a combination of compatibility libraries, semantic patches, and regular patches.
