> Currently EC policy is stored as in the raw xattr namespace. It would be
> better to store this in "system" like storage policy.
> Raw is meant for attributes which need to be preserved across a distcp, like
> encryption info. EC policy is more similar to replication factor or storage
> policy, which can differ between the src and target of a distcp.
