    Pull vfs updates from Al Viro:
     "In this one:
    
       - d_move fixes (Eric Biederman)
    
       - UFS fixes (me; locking is mostly sane now, a bunch of bugs in error
         handling ought to be fixed)
    
       - switch of sb_writers to percpu rwsem (Oleg Nesterov)
    
       - superblock scalability (Josef Bacik and Dave Chinner)
    
       - swapon(2) race fix (Hugh Dickins)"
