mm: fix the try_to_unmap prototype for !CONFIG_MMU

Christoph Hellwig · torvalds · commit ab7965de1725 · 2021-07-15T10:13:49.000-07:00
Adjust the nommu stub of try_to_unmap to match the changed protype for the full version. Turn it into an inline instead of a macro to generally improve the type checking.
