Oh, we're doing review of the XFS/iomap folio patches, which led to
looking at zero_user_segments(), and I realised that memzero_page()
was now functionally identical to zero_user(). And you'd been quite
specific about not having flush_dcache_page() in there, so ... I wondered
if you'd had a change of mind.
