Description

Looks like the code appends the full legacy key to the new prefix rather that use the user-provided OMAP name from the tail of the key.
So the resulting key gets the following format:
<new key prefix: <pool_id, hash, onode_nid>> + '.' + <legacy key prefix: <nid>> + '.' + <user name>
while the expected one is:
<new key prefix: <pool_id, hash, onode_nid>> + '.' + <user name>
