drbd0: Writing meta data super block now.

crypto type=3
drbd0: conn( StandAlone -> Unconnected ) 

I got the message "not a digest", which is correct.
We are using CRYPTO_TYPE_HASH, which in turn uses
CRYPTO_TYPE_DIGEST.

Eh, never mind my babling, just this:

s/CRYPTO_ALG_TYPE_DIGEST/CRYPTO_ALG_TYPE_HASH/g

then it probably works (I've removed the goto fail and just
printed the type, which was a HASH :-) ).
