The 2nd parameter in __page_set_anon_rmap() is only used by

Remove SetPageAnonExclusive() from __page_set_anon_rmap() and modify
__page_set_anon_rmap() to __folio_set_anon_rmap().

Since __page_check_anon_rmap() needs a folio, we can directly use
and change it to __folio_check_anon_rmap().


Leaking the SetPageAnonExclusive() into all callers is not an improvement.

Not convinced we want this patch TBH. Tentative NAK.
