From a4d1a885251382250ec315482bdd8ca52dd61e6a Mon Sep 17 00:00:00 2001 From: Jérôme Glisse Date: Thu, 31 Aug 2017 17:17:26 -0400 Subject: dax: update to new mmu_notifier semantic MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Replace all mmu_notifier_invalidate_page() calls by *_invalidate_range() and make sure it is bracketed by calls to *_invalidate_range_start()/end(). Note that because we can not presume the pmd value or pte value we have to assume the worst and unconditionaly report an invalidation as happening.
