The routine vfs_clean_pages() is only called by bdwrite() to tell the VM that the buffer pages are "clean" so that VFS will write them when it sees fit. However, pages belonging to buffers are wired down, which means they are not on any paging queues. So even without vfs_clean_pages(), the pageout daemon will not write those pages. There is therefore no need for the call to vfs_clean_pages(). Please correct me if I am wrong. I am really confused here.
