    hammer2 - Fix cluster synchronization bug (2+ nodes)
    
    * Fix a bug where hammer2_cluster_check() can end up in an infinite
      loop.
    
    * Look for pfs_names[] in all PFSs associated with a cluster.
    
    * Add missing xop retirement in pfs-delete.
    
    * Skip the directory empty check in pfs-delete.
    
    * Preliminary code to deallocate an element of a live PFS
