From f5777bc2d9cf0712554228b1a7927b6f13f5c1f0 Mon Sep 17 00:00:00 2001 From: Qian Cai Date: Thu, 28 Mar 2019 20:44:21 -0700 Subject: mm/page_isolation.c: fix a wrong flag in set_migratetype_isolate() Due to has_unmovable_pages() taking an incorrect irqsave flag instead of the isolation flag in set_migratetype_isolate(), there are issues with HWPOSION and error reporting where dump_page() is not called when there is an unmovable page.
