Subject: [PATCH] mm: fix the try_to_unmap prototype for !CONFIG_MMU
Date: Mon,  5 Jul 2021 07:39:44 +0200	[thread overview]
Message-ID: <20210705053944.885828-1-hch@lst.de> (raw)

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.

Fixes: 1fb08ac63bee ("mm: rmap: make try_to_unmap() void function")
