Hi all,

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

Caused by API updates in the keys tree without fixups of their uses.

The keys tree is now based on v5.5-rc3 ...

The callis to keyring_alloc() in fs/verity/signature.c and
fs/crypto/keyring.c were added in v5.4-rc1. As were the calls to
request_key() in fs/crypto/keysetup_v1.c and
drivers/md/dm-verity-verify-sig.c.

I have used the keys tree from next-20191211 again today.
