Hi all,

After merging the akpm-current tree, today's linux-next build (x86_64
allmodconfig) failed like this:

mm/kasan/quarantine.c: In function 'quarantine_put':
mm/kasan/quarantine.c:207:15: error: 'info' undeclared (first use in this function)
207 | qlink_free(&info->quarantine_link, cache);
| ^~~~

Caused by commit

120d593a8650 ("kasan: fix memory leak of kasan quarantine")

interacting with commit

cfbc92088e1d ("kasan: rename get_alloc/free_info")

Can we please get this sorted out once and for all?

I have applied the following patch for today:

From: Stephen Rothwell <sfr@canb.auug.org.au>
