Subject: [Question Resend] About z3fold page migration
Date: Mon, 12 Oct 2020 14:00:17 +0000	[thread overview]
Message-ID: <6d803d0cf27840caa64619949c2c3dd1@huawei.com> (raw)

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. :)
