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.
