I did not say that all pa_memblock_acquire() calls would be for
memchunks, I said that (almost?) all pa_memblock_acquire_index() calls
would be memchunks. Is that a problem? The purpose wouldn't be to
replace pa_memblock_acquire(), the purpose would be to replace the
pa_memblock_acquire_index() helper.
