(Eric Biggers) * Update the changelog (PATCH8). (Rafael Wysocki) A couple of other things outside of these patches are still in progress: * Support DM-crypt/cryptsetup for Key Locker usage (Andy Lutomirski) [2]. * Understand decryption under-performance (Eric Biggers and Milan Broz) [3][4]. This feature's usage for the threat model can be found in the previous cover letter [1]. This version is based on 5.16.
