The spacing is all over the place, I'm afraid.  Can you send it again?

For example, the vertical bars in the right-hand column don't align:

|  [spin_lock(&key_serial_lock)]      |[mutex_lock(&key_user_keyr..mutex)]
|  |                                       ||
|  atomic_read() == 0                 ||
|  |{ rb_ease(&key->serial_node,) }   ||
|  |                                       ||
|  [spin_unlock(&key_serial_lock)]    |find_keyring_by_name()
|  |                                       |||
