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. Link: http://lkml.kernel.org/r/20190320204941.53731-1-cai@lca.pw Fixes: d381c54760dc ("mm: only report isolation failures when offlining memory") Acked-by: Michal Hocko <mhocko@suse.com> Reviewed-by: Oscar Salvador <osalvador@suse.de> Signed-off-by: Qian Cai <cai@lca.pw> Cc: <stable@vger.kernel.org> [5.0.x] Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
