ABDs which don't own their data (for instance the ones which were
allocated through abd_get_offset() and abd_get_from_buf()). If an
ABD takes ownership of its buf then it will become tracked.

Total number of bytes that *would have been* consumed by ARC
buffers in the arc_mru_ghost state. The key thing to note
here, is the fact that this size doesn't actually indicate
RAM consumption. The ghost lists only consist of headers and
don't actually have ARC buffers linked off of these headers.
Thus, *if* the headers had associated ARC buffers, these
buffers *would have* consumed this number of bytes.
