options for caching on open()

I have a patch to the overlay fs that allows you to
cache on open() rather than writing to the storage directory
only on write().

On implementation of caching on open() for the ovlfs
(overlay fs), there is a rather long delay for copying
the file to cache. Can you fork the cache and open the
file on the original media to avoid the long delay
in the cache? Right now, it caches, copies, and
then open the cached file. Are there other approaches
to a caching option that are better?

Thanks,
Scott
