Hi all,

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

drivers/md/dm-verity-verify-sig.c: In function 'verity_verify_get_sig_from_key':
drivers/md/dm-verity-verify-sig.c:38:8: error: too few arguments to function 'request_key'
  key = request_key(&key_type_user,
        ^~~~~~~~~~~
In file included from include/keys/user-type.h:11,
                 from drivers/md/dm-verity-verify-sig.c:10:
include/linux/key.h:318:27: note: declared here
 static inline struct key *request_key(struct key_type *type,
                           ^~~~~~~~~~~

Caused by commit

  f802f2b3a991 ("keys: Replace uid/gid/perm permissions checking with an ACL")

interacting with commit

  644332ceab35 ("dm verity: add root hash pkcs#7 signature verification")

from the device-mapper tree.

I applied the following merge resolution patch.
