When KCOV is enabled all functions get instrumented, unless the __no_sanitize_coverage attribute is used. To prepare for __no_sanitize_coverage being applied to __init functions, we have to handle differences in how GCC's inline optimizations get resolved. For s390 this requires forcing a couple functions to be inline withI assume you mean powerpc here, though I'm sure my employer is happy that you're at least confusing us with IBM's other architecture :)
Whoops! Yes. Paste-o on my part. The rest of the sentence was updated correctly though. :) -- Kees Cook
