Revision 783657a7dc20e5c0efbc9a09a9dd38e238a723da authored by Naoya Horiguchi on 29 November 2012, 21:54:34 UTC, committed by Linus Torvalds on 30 November 2012, 16:51:18 UTC
When we try to soft-offline a thp tail page, put_page() is called on the tail page unthinkingly and VM_BUG_ON is triggered in put_compound_page(). This patch splits thp before going into the main body of soft-offlining.
