This commit needs to prereq commit ee618b4619b7 "KEYS: trusted: sanitize all key material".
Thanks, that fixes the issue for 4.4 and 4.9, but not for 3.18 :(
Commit 146aa8b "KEYS: Merge the type-specific data with the payload data" introduced the change trusted_destroy(), but it is a rather big patch.

David? Otherwise, Eric could you create a patch that applies directly to the stable tree linux-3.18.y?
thanks,
