| Subject: mm/kmemleak.c: fix unused-function warning |
| |
| From: Arnd Bergmann <arnd@arndb.de> |
| |
| commit dce5b0bdeec61bdbee56121ceb1d014151d5cab1 upstream. |
| |
| 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. |
| |
| Link: http://lkml.kernel.org/r/20190416123148.3502045-1-arnd@arndb.de |
| Fixes: 298a32b13208 ("kmemleak: powerpc: skip scanning holes in the .bss section") |
