You're doing this the hard way, which makes life hard for the reviewrs.
patch 1. Introduce folio->_last_cpupid
patch 2: Add
static inline int folio_xchg_access_time(struct folio *folio, int time)
{
return xchg_page_access_time(&folio->page, time);
}
patch 3-n: Convert callers
Patch n+1: Remove xchg_page_access_time(), folding it into
folio_xchg_access_time().
Similarly for page_cpupid_xchg_last / folio_cpupid_xchg_last().
(why is this not called folio_xchg_last_cpupid?)
