Extend the SED block driver so it can alternatively obtain a key from a sed-opal kernel keyring. The SED ioctls will indicate the source of the key, either directly in the ioctl data or from the keyring. This allows the use of SED commands in scripts such as udev scripts so that drives may be automatically unlocked as they become available.
