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

Hi James,

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

fs/cifs/cifs_spnego.c: In function 'init_cifs_spnego':
fs/cifs/cifs_spnego.c:206:12: error: too few arguments to function 'keyring_alloc'
  keyring = keyring_alloc(".cifs_spnego",
            ^
In file included from include/linux/cred.h:17:0,
                 from include/linux/sched.h:56,
                 from include/linux/kasan.h:4,
                 from include/linux/slab.h:118,
                 from fs/cifs/cifs_spnego.c:23:
include/linux/key.h:302:20: note: declared here
 extern struct key *keyring_alloc(const char *description, kuid_t uid, kgid_t gid,
                    ^

Caused by commit

  5b82c5cbcfe4 ("cifs: Create dedicated keyring for spnego operations")

from the cifs tree interacting with commit

  5ac7eace2d00 ("KEYS: Add a facility to restrict new links into a keyring")

from the security tree.

I added the following merge fix patch (and someone will have to let
Linus know):
