A Dfiles.rst11 with a lock (files->file_lock) and reference count (files->count).
12 ->file_lock protected accesses to all the file related fields
61 3. For any update to the fd table, files->file_lock must
110 holding files->file_lock. If ->file_lock is dropped, then
116 spin_lock(&files->file_lock);
