I think I need to implement orangefs_readahead
and from there fire off an asynchronous read
and while that's going I'll call readahead_page
with a rac that I've cranked up with readahead_expand
and when the read gets done I'll have plenty of pages
for the large IO I did.

Would the netfs helper lib in patches 5-13 here be of use to orangefs?  Most
of the information about it is on patch 8.
