mm/memory.c: mark create_huge_pmd() inline to prevent build failure
With gcc 4.1.2: mm/memory.o: In function `create_huge_pmd': memory.c:(.text+0x93e): undefined reference to `do_huge_pmd_anonymous_page' Interestingly, create_huge_pmd() is emitted in the assembler output, but never called. Converting transparent_hugepage_enabled() from a macro to a static inline function reduced the ability of the compiler to remove unused code. Fix this by marking create_huge_pmd() inline. Fixes: 16981d763501c0e0 ("mm: improve readability of transparent_hugepage_enabled()") Link: http://lkml.kernel.org/r/1499842660-10665-1-git-send-email-geert@linux-m68k.org Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org> Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
