Re: [PATCH v3 06/13] arm64: Handle KCOV __init vs inline mismatches

Hey Kees,

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 arm64 this requires forcing one function to be inline with __always_inline.

Please can you spell out the issue a bit more here? From the description you've given, I can't figure out why acpi_get_enable_method() is the only function that needs fixing up so I worry that this could be fragile.

Thanks,

Will
