From 6b49bf6ddbb0d7992c816846acfa5fd1cf751c36 Mon Sep 17 00:00:00 2001 From: Alistair Popple Date: Wed, 30 Jun 2021 18:54:19 -0700 Subject: mm: rename migrate_pgmap_owner MMU notifier ranges have a migrate_pgmap_owner field which is used by drivers to store a pointer. This is subsequently used by the driver callback to filter MMU_NOTIFY_MIGRATE events. Other notifier event types can also benefit from this filtering, so rename the 'migrate_pgmap_owner' field to 'owner' and create a new notifier initialisation function to initialise this field.
