From 31c5bda3a656089f01963d290a40ccda181f816e Mon Sep 17 00:00:00 2001 From: Dan Williams Date: Thu, 26 Jul 2018 16:37:22 -0700 Subject: [PATCH] mm: fix exports that inadvertently make put_page() EXPORT_SYMBOL_GPL MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Commit e76384884344 ("mm: introduce MEMORY_DEVICE_FS_DAX and CONFIG_DEV_PAGEMAP_OPS") added two EXPORT_SYMBOL_GPL() symbols, but these symbols are required by the inlined put_page(), thus accidentally making put_page() a GPL export only. This breaks OpenAFS (at least). Mark them EXPORT_SYMBOL() instead.
