That's a question for the netfs designers. CacheFS doesn't care. There are
plans afoot to permit the netfs to log uncommitted changes in the cache, but
it's up to the netfs to dictate how they're used.

CacheFS is hidden from the user by the netfs. As far as the user is concerned,
CacheFS does not exist, except to affect performance of the netfs. Think of it
like this:
