Add these helper functions, and export them for filesystem use.

What is the point of adding these wrappers vs just calling the
underlying functions?

I added them so that they can be called in a friendly way, even if
CONFIG_DAX is off.  Otherwise, we need #if IS_ENABLED(CONFIG_DAX) to wrap
them where they are called.

No need for wrappers, you can stub out the underlying functions as well.
