  As commit a83f0551f496 ("mm/vmscan: convert reclaim_pages() to use
a folio") changes the arg from page_list to folio_list, but not
the defination, let's correct it and rename it to reclaim_folios too.

I didn't bother.  It's not inaccurate; we're reclaiming the pages
in the folios.

OK, keep the name seems better, there is another similar issue in
reclaim_clean_pages_from_list(), I will only unify the arg between
definition and declaration.>

What's the general rule about renaming "pages" to "folios" in function
names?  I am thinking whether it's necessary to rename migrate_pages()
to migrate_folios().  It's unnecessary?

Best Regards,
Huang, Ying
