Why not move that into madvise_pageout_page_range() ? Avoids passing
this variable to that function.
In fact, why not even call that function directly instead of storing
that in madvise_walk_private(). The function is extremely lightweight.
lru_add_drain();
tlb_gather_mmu(&tlb, mm);
- madvise_pageout_page_range(&tlb, vma, start_addr, end_addr);
+ madvise_pageout_page_range(&tlb, vma, start_addr, end_addr, can_pageout_file);
tlb_finish_mmu(&tlb);
return 0;
