Hi all,
After merging the akpm tree, today's linux-next build (x86_64
allmodconfig) failed like this:
mm/kasan/quarantine.c: In function 'quarantine_put':
mm/kasan/quarantine.c:197:15: error: 'info' undeclared (first use in this function)
197 | qlink_free(&info->quarantine_link, cache);
| ^~~~
mm/kasan/quarantine.c:197:15: note: each undeclared identifier is reported only once for each function it appears in
mm/kasan/quarantine.c:199:3: error: 'return' with no value, in function returning non-void [-Werror=return-type]
199 | return;
| ^~~~~~
mm/kasan/quarantine.c:171:6: note: declared here
171 | bool quarantine_put(struct kmem_cache *cache, void *object)
| ^~~~~~~~~~~~~~
Caused by patches
"kasan: rename get_alloc/free_info"
"kasan: sanitize objects when metadata doesn't fit"
I have applied the following fix patch:
