Gack, ftrace_page would probably be better off simply using the flex list 
implementation I suggested which constructs a list from page->lru since it 
doesn't appear to require indexing into the array, it simply requires an 
iteration in all cases (or am I wrong?).  Flex lists could easily be made 
to support seqfiles.
