OpenZFS is growing native encryption support and I am confident that the cache encryption is properly handled there. But you don= 't have to take my word for it. In any case, the proposed design is a big layering violation and is much harder to implement that it may sound. So, = we are not going to do it. If you had a patch, then it could be a slightly different story. But only slightly. --=20 You are receiving this mail because: You are the assignee for the bug.=
