Don't hide structure definitions under conditional compilation, it only
makes messier and harder to maintain. Move struct
dmabuf_genpool_chunk_owner definition out of CONFIG_NET_DEVMEM ifdef
together with a bunch of trivial inlined helpers using the structure.
To be honest I think the way it is is better? Having the struct
defined but always not set (because the code to set it is always
compiled out) seem worse to me.
Is there a strong reason to have this? Otherwise maybe drop this?
I can drop it if there are strong opinions on that, but I'm
allergic to ifdef hell and just trying to help to avoid it becoming
so. I even believe it's considered a bad pattern (is it?).
As for a more technical description "why", it reduces the line count
and you don't need to duplicate functions. It's always annoying
making sure the prototypes stay same, but this way it's always
compiled and syntactically checked. And when refactoring anything
like the next patch does, you only need to change one function
but not both. Do you find that convincing?
