From: Christoph Hellwig <hch@xxxxxx> Subject: mm: unexport follow_pte_pmd Patch series "simplify follow_pte a bit". This small series drops the not needed follow_pte_pmd exports, and simplifies the follow_pte family of functions a bit. This patch (of 2): follow_pte_pmd() is only used by the DAX code, which can't be modular.
