I think this may have changed behavior, but I'm not sure.

Description says modernize, but I also see a some null checking being added that seems unrelated to the modernizing.

> Source/WebCore/loader/DocumentLoader.cpp:809
> +        if (m_substituteData.content() && m_substituteData.content()->size())
> +            dataReceived(nullptr, m_substituteData.content()->data(), m_substituteData.content()->size());

Given that we dereference it three times after checking it for null, maybe put the pointer into a local variable?

> Source/WebCore/loader/ResourceLoader.cpp:310
> +        m_resourceData->append(buffer);

Should append take a SharedBuffer& instead of a SharedBuffer*?

> Source/WebCore/loader/SubstituteData.h:58
> -        const SharedBuffer* content() const { return m_content.get(); }
> +        SharedBuffer* content() const { return m_content.get(); }

What’s the rationale behind this change?

> Source/WebCore/platform/SharedBuffer.cpp:111
>      RefPtr<SharedBuffer> buffer = create();

Should use auto.

> Source/WebCore/platform/SharedBuffer.cpp:291
> +    Ref<DataBuffer> newBuffer = adoptRef(*new DataBuffer);

Should use auto.

> Source/WebCore/platform/SharedBuffer.h:61
> +    WEBCORE_EXPORT static RefPtr<SharedBuffer> adoptVector(Vector<char>&);

This should return a Ref, not a RefPtr.

This was needed because of the lack of https://bugs.webkit.org/show_bug.cgi?id=158269 at some point while working on this patch, but I don't think it's needed any more.  Removing.
