I have test this series together with ceph side PR#1 and worked well for me. LGTM.I've not posted this in a while, so I figured it was a good time to do so. This patchset is a pile of the mostly settled parts of the fscrypt integration series. With this, pretty much everything but the actual content encryption in files now works. This series is also in the wip-fscrypt-size branch of the ceph-client tree: https://github.com/ceph/ceph-client/tree/wip-fscrypt-size It would also be nice to have an ack from Al Viro on patch #1, and from Eric Biggers on #2-5. Those touch code outside of the ceph parts. If they aren't acceptable for some reason, I'll need to find other ways to handle them.
