Description

If we take a snapshot and the SnapRealm includes a remote hard link, the remote inode doesn't get snapshotted. That's not necessarily a dealbreaker (though it is surprising to users), but it is also not handled well by any of our code. We just changed things so that the MDS would print a warning message rather than asserting (I didn't work out exactly how the client will handle this situation); we really need to design and handle it more deliberately than that.
