From: Arnd Bergmann <arnd@xxxxxxxx> Subject: mm/kmemleak.c: fix unused-function warning The only references outside of the #ifdef have been removed, so now we get a warning in non-SMP configurations: mm/kmemleak.c:1404:13: error: unused function 'scan_large_block' [-Werror,-Wunused-function] Add a new #ifdef around it.
