From 4dd845b5a3e57ad07f26ef808707b064696fe34b Mon Sep 17 00:00:00 2001 From: Alistair Popple Date: Wed, 30 Jun 2021 18:54:09 -0700 Subject: mm/swapops: rework swap entry manipulation code Both migration and device private pages use special swap entries that are manipluated by a range of inline functions. The arguments to these are somewhat inconsistent so rework them to remove flag type arguments and to make the arguments similar for both read and write entry creation.
