Hi all:
Many thanks for brilliant z3fold code. I am reading it and have some
questions about it. It's very nice of you if you can explain it for me.
1.page->private is used in z3fold but PagePrivate flag is never set,
should we SetPagePrivate for it?
2.Since PagePrivate flag is never set, why we ClearPagePrivate in
free_z3fold_page and z3fold_page_migrate?
3.Should we add page to the unbuddied list in z3fold_page_putback()
when zhdr->refcount does not reach 0 since we remove it from unbuddied list
in z3fold_page_isolate? Or When we will add page to the unbuddied list after
z3fold_page_putback?
Thanks a lot in advance. And waiting for your kindly reply. :)
