don't bother with call_rcu() in put_files_struct() At that point nobody can see us anyway; everything that looks at files_fdtable(files) is separated from the guts of put_files_struct(files) - either since files is current->files or because we fetched it under task_lock() and hadn't dropped that yet, or because we'd bumped files->count while holding task_lock()...
