Hi Arnd,
is this a replacement for __maybe_unused annotations that we would typically use to address these? Is the ternary operator in PTR_IF enough to eliminate the warning? Does that work the same way for structure definitions as it does for conditionals where we use IS_ENABLED() to use the compiler's DCE for improved coverage?
Yes to all three.
It looks like it, but just making sure because there's another patch that fixes this warning by adding __maybe_unused.
I sent a lot of patches in the past to add __maybe_unused, but this was mainly because we could never come up with a good replacement. Paul Cercueil has finally come up with a good solution, so this is how we should do it from now on.
