Looking closer at this, I'd say that files_lock should be replaced by locking of the respective lists (struct sb->s_files and struct tty_struct->tty_files, unless I'm mistaken), and that this locking should be done with semaphores. Right? Going through the list of all sb->s_files can be a costly operation; it may be worthwile to have a per-sb locking mechanism for that.
