Subject: [PATCH 1/3] mm: Print head flags in dump_page
Date: Mon, 29 Jun 2020 16:19:16 +0100 [thread overview]
Message-ID: <20200629151918.15537-2-willy@infradead.org> (raw)
In-Reply-To: <20200629151918.15537-1-willy@infradead.org>
Tail page flags contain very little useful information. Print the head
page's flags instead (even though PageHead is a little misleading).
