Subject: [PATCH] kmemleak: fix unused-function warning
Date: Tue, 16 Apr 2019 14:31:24 +0200 [thread overview]
Message-ID: <20190416123148.3502045-1-arnd@arndb.de> (raw)
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.
Fixes: 298a32b13208 ("kmemleak: powerpc: skip scanning holes in the .bss section")
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
