Subject: [RESEND PATCH] mm: fix a wrong flag in set_migratetype_isolate()
Date: Wed, 20 Mar 2019 16:49:41 -0400
Message-ID: <> (raw)

Due to has_unmovable_pages() takes an incorrect irqsave flag instead of
the isolation flag in set_migratetype_isolate(), it causes issues with
HWPOSION and error reporting where dump_page() is not called when there
is an unmoveable page.

Fixes: d381c54760dc ("mm: only report isolation failures when offlining memory")
Cc: # 5.0.x
