A few comments that didn't fit anywhere else:
I'm looking forward to contents encryption, as that's the most important part.
Is there any possibility that the fscrypt xfstests can be run on ceph?
See: https://www.kernel.org/doc/html/latest/filesystems/fscrypt.html#tests
In fs/ceph/Kconfig, CEPH_FS needs:
select FS_ENCRYPTION_ALGS if FS_ENCRYPTION
There are compile errors when !CONFIG_FS_ENCRYPTION.
