   4 Subject: mm/kmemleak.c: fix unused-function warning
   5
   6 From: Arnd Bergmann <arnd@arndb.de>
   7
   8 commit dce5b0bdeec61bdbee56121ceb1d014151d5cab1 upstream.
   9
  10 The only references outside of the #ifdef have been removed, so now we
  11 get a warning in non-SMP configurations:
  12
  13   mm/kmemleak.c:1404:13: error: unused function 'scan_large_block' [-Werror,-Wunused-function]
  14
  15 Add a new #ifdef around it.
