Can you rename these files please? The 'keys' prefix is redundant. They're
obviously about keys, or they shouldn't be in this directory. I'd suggest
something like 'ecryptfs_format.[ch]'.
You might want to make a subdir here specifically for the trusted and
encrypted keys and all their formats and move those files into it if you're
going to have lots of formats.

I think we need an additional key type operation - one that allows you to pass
judgement on the description to be given for a key in key_alloc(). On the
other hand, this doesn't help here as you can't do a full check on the key
description without the payload.
