Subject: linux-next: build failure after merge of the kspp tree

Hi all,

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

security/apparmor/file.c: In function 'aa_path_link':
security/apparmor/file.c:475:23: error: positional initialization of field in 'struct' declared with 'designated_init' attribute [-Werror=designated-init]
  struct path link = { new_dir->mnt, new_dentry };
                       ^

Caused by commit

  1a12979f61e4 ("randstruct: Mark various structs for randomization")

interacting with commit

  8014370f1257 ("apparmor: move path_link mediation to using labels")

from the security tree.

I added the following merge fix patch for today:
