But I can't see how can be useful marking the page PG_referenced before
return 0 if the page is young. It's not a swap cache page, it's not a
freeable page and shrink_mmap() can do nothing with it.
if (pte_young(pte)) {
/*
* Transfer the "accessed" bit from the page
* tables to the global page map.
*/
set_pte(page_table, pte_mkold(pte));
set_bit(PG_referenced, &page_map->flags);
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
return 0;
}
Am I missing something again ? ;)
