thp: move shmem_huge_enabled() outside of SYSFS ifdef
The newly introduced shmem_huge_enabled() function has two definitions, but neither of them is visible if CONFIG_SYSFS is disabled, leading to a build error: mm/khugepaged.o: In function `khugepaged': khugepaged.c:(.text.khugepaged+0x3ca): undefined reference to `shmem_huge_enabled' This changes the #ifdef guards around the definition to match those that are used in the header file. Fixes: e496cf3d7821 ("thp: introduce CONFIG_TRANSPARENT_HUGE_PAGECACHE") Link: http://lkml.kernel.org/r/20160809123638.1357593-1-arnd@arndb.de Signed-off-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Kirill A.
