Where possible you should try to split your series up such that each
is useful individually - splitting things up by file is mostly done for
the addition of large new blocks of code.  This means that the patches
can be applied one at a time without leaving the tree in an
"interesting" state.

For example, a patch adding the cache operations but supporting only the
current flat cache would introduce the cache API and factor out some
code usefully by itself.
