From 54a75157d97976f35e63e37e31e39bda622cbf39 Mon Sep 17 00:00:00 2001 From: "Matthew Wilcox (Oracle)" Date: Thu, 6 Aug 2020 23:19:48 -0700 Subject: mm/debug: print hashed address of struct page The actual address of the struct page isn't particularly helpful, while the hashed address helps match with other messages elsewhere. Add the PFN that the page refers to in order to help diagnose problems where the page is improperly aligned for the purpose.
