I believe this is the crucial point.

I have my own concerns about the use of preprocessor macros, which goes
against the basic idea of a code tagging framework (patch 13/40).
AFAICS the CODE_TAG_INIT macro must be expanded on the same source code
line as the tagged code, which makes it hard to use without further
macros (unless you want to make the source code unreadable beyond
imagination). That's why all allocation functions must be converted to
macros.

If anyone ever wants to use this code tagging framework for something
else, they will also have to convert relevant functions to macros,
slowly changing the kernel to a minefield where local identifiers,
struct, union and enum tags, field names and labels must avoid name
conflict with a tagged function. For now, I have to remember that
alloc_pages is forbidden, but the list may grow.

FWIW I can see some occurences of "alloc_pages" under arch/ which are
not renamed by patch 19/40 of this series. For instance, does the
kernel build for s390x after applying the patch series?

New code may also work initially, but explode after adding an #include
later...

HOWEVER, if the rest of the community agrees that the added value of
code tagging is worth all these potential risks, I can live with it.
