Hi David,

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

security/integrity/digsig.c: In function 'integrity_init_keyring':
security/integrity/digsig.c:46:30: error: passing argument 7 of 'keyring_alloc' from incompatible pointer type [-Werror=incompatible-pointer-types]
 #define restrict_link_to_ima restrict_link_by_builtin_and_secondary_trusted
                              ^
security/integrity/digsig.c:95:9: note: in expansion of macro 'restrict_link_to_ima'
         restrict_link_to_ima, NULL);
         ^
In file included from include/linux/cred.h:17:0,
                 from security/integrity/digsig.c:18:
include/linux/key.h:311:20: note: expected 'struct key_restriction *' but argument is of type 'int (*)(struct key *, const struct key_type *, const union key_payload *, struct key *)'
 extern struct key *keyring_alloc(const char *description, kuid_t uid, kgid_t gid,
                    ^

Caused by commits

  aaf66c883813 ("KEYS: Split role of the keyring pointer for keyring restrict functions")
  c5faca6b4a58 ("KEYS: Use structure to capture key restriction function and data")

I have used the version from next-20170403 for today.
