 /******************************************************************************************
  * This function creates a new couple dentry/inode, and insert it in the Inode-Tree.
- * It can be executed by any thread running in any cluster, as this function
- * uses the rpc_dentry_create_client() and rpc_inode_create client() if required.
- * This is done in three steps:
+ * It can be executed by any thread running in any cluster ( can be differente from both
+ * the child cluster and the parent cluster), as it uses the rpc_dentry_create_client()
+ * and rpc_inode_create client() if required. This is done in three steps:
  * 1) The dentry is created in the cluster containing the existing <parent_xp> inode.
  *    The new dentry name is defined by the <name> argument.
