Subject: [PATCH 3/3] mm: Print hashed address of struct page
Date: Mon, 29 Jun 2020 16:19:18 +0100 [thread overview]
Message-ID: <20200629151918.15537-4-willy@infradead.org> (raw)
In-Reply-To: <20200629151918.15537-1-willy@infradead.org>
The actual address of the struct page isn't particularly helpful,
while the hashed address helps match with other messages elsewhere.
