Pull keyring updates from David Howells: - Fix a documentation warning. - Replace a zero-length array with a flexible one - Make the big_key key type use ChaCha20Poly1305 and use the crypto algorithm directly rather than going through the crypto layer. - Implement the update op for the big_key type. * tag 'keys-next-20200602' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs: keys: Implement update for the big_key type security/keys: rewrite big_key crypto to use library interface KEYS: Replace zero-length array with flexible-array Documentation: security: core.rst: add missing argument
