Subject: Re: [PATCH 01/10] mm/page-flags: introduce PageHighMemZone()
Date: Tue, 21 Apr 2020 02:00:05 -0700 [thread overview]
Message-ID: <20200421090005.GA23085@infradead.org> (raw)

I don't think the names are very good. I'd keep PageHighMem for the
existing highmem zone, and add something like PageDirectMapped or
similar for ay page that has a valid direct mapping address. This will
also come in handy if we plan to go ahead with the xpfo work.
