int nfs_revalidate_file_size (struct inode * inode, struct file * filp);
inode - pointer to inode struct file - pointer to struct file
Revalidates the file length. This is basically a wrapper around nfs_revalidate_inode that takes into account the fact that we may have cached writes (in which case we don't care about the server's idea of what the file length is), or O_DIRECT (in which case we shouldn't trust the cache).
