With the support for loading of backends as modules, the
cleancache_enabled is always set to true. The next subsequent patches
are going to convert the cleancache_enabled to be a bit more selective
and be on/off depending on whether the backend has registered - and not
whether the cleancache API is enabled.
The three functions: cleancache_init_[shared|]fs and
cleancache_invalidate_fs can be called anytime - they queue up which
of the filesystems are active and can use the cleancache API - and when
the backend is registered they will know which filesystem to
process.
