The new_node_page() is processed as the following procedure. 1. A new node page is allocated. 2. Set PageUptodate with proper footer information. 3. Check if there is a free space for allocation 4.a. If there is no space, f2fs returns with -ENOSPC. 4.b. Otherwise, go next. In the case of step #4.a, f2fs remains a wrong node page in the page cache with the uptodate flag. So, we should remove the uptodate flag, if allocation is failed.
