Hi Chuck, In the context of doing a copy between different "types" of filesystems, it was pointed out to me that NFS has many types: nfs4_fs_type, nfs4_remote_fs_type, nfs4_remote_referral_fs_type, nfs4_referral_fs_type. So doing a simple check that fs type of "in" and "out" might not be sufficient. Do you see any issues allowing a copy offload between different types? Basically checking that "in" and "out" descriptions come from any of the these types? Thank you.
