Peng Tao 363090e74f staging/lustre/llite: fix mkdir endless loop ... Running on 3.11-rc4 kernel, I got below endless loop. It turns to be that Lustre always saves the first page of a dir inode mapping at index ~0UL. And after commit 5a720394 (mm: teach truncate_inode_pages_range() to handle non page aligned ranges), truncate_inode_pages_range() _NO LONGER_ truncates the page that is sitting at index ~0UL.
