Description
It seems the API is still fs-specific ioctls, but there's repeated discussion about reflink(2).
If a nice common API arises, or if we're willing to have our own Ceph-specific ioctl, there's some interest for having reflink functionality out there.

This feature would really be appreciated. We would like to switch to Ceph for our cluster storage, but we rely heavily on reflink copies for large versioned datasets.
