Revision 48db54ee2f41e8ae2faf330b55db34a9fffb5b3c authored by Minchan Kim on 01 February 2011, 23:52:33 UTC, committed by Linus Torvalds on 03 February 2011, 00:03:18 UTC
If migrate_huge_page by memory-failure fails , it calls put_page in itself to decrease page reference and caller of migrate_huge_page also calls putback_lru_pages. It can do double free of page so it can make page corruption on page holder. In addtion, clean of pages on caller is consistent behavior with migrate_pages by cf608ac19c ("mm: compaction: fix COMPACTPAGEFAILED counting").
