It also eliminates the concern I had about using the value
of "lip" after falling off the front of the list with a
list_for_each_entry_reverse().  A null pointer signifies
no entry has a lower lsn than the one provided, and
that covers both the "empty list" and the "lower than
all other lsn's in the list" cases.

I think you should base your solution on Christoph's
approach, Dave.
