    nfsd4: remove lockowner when removing lock stateid · a1b8ff4c
    J. Bruce Fields authored
    The nfsv4 state code has always assumed a one-to-one correspondance
    between lock stateid's and lockowners even if it appears not to in some
    places.
    
    We may actually change that, but for now when FREE_STATEID releases a
    lock stateid it also needs to release the parent lockowner.
    
    Symptoms were a subsequent LOCK crashing in find_lockowner_str when it
    calls same_lockowner_ino on a lockowner that unexpectedly has an empty
    so_stateids list.
