Dear Willem,

I agree that this change makes cherry picking harder. When keeping the
order of the code, the following commits have to introduce many pairs
"#ifdef CONFIG_NET - #endif" and "#if defined(CONFIG_NET) ||Â
defined(CONFIG_SECCOMP_FILTER) #endif"
This is how I developed the commits, but then refactored for improved
readability.

From my experience, cherry picking changes from this variant is equally
difficult. A third alternative, splitting the files into separate files,
would force me to make current static definitions visible.

I am happy to go another route, if people insist that this is the better
way forward.

Best,
Norbert
