mm: vmscan: convert folio_referenced() to use vma_flags_t
Patch series "promote mapped executable folios after first usage for
MGLRU", v4.
Now MGLRU's protection of mapped executable file folios is less reliable.
Follow the classical LRU's logic, promoting mapped executable file folios
after their first usage to give executable code a better chance to stay in
memory and improve workload performance (See patch 2 for more details).
This patch (of 3):
Replace use of the legacy vm_flags_t flags with vma_flags_t values for
folio_referenced() and related logic. This is also a preparation for the
following changes.
No functional changes.
