    [GFS2] Remove remote lock dropping code · 1bdad606

    There are several reasons why this is undesirable:
    
     1. It never happens during normal operation anyway
     2. If it does happen it causes performance to be very, very poor
     3. It isn't likely to solve the original problem (memory shortage
        on remote DLM node) it was supposed to solve
     4. It uses a bunch of arbitrary constants which are unlikely to be
        correct for any particular situation and for which the tuning seems
        to be a black art.
     5. In an N node cluster, only 1/N of the dropped locked will actually
        contribute to solving the problem on average.
    
    So all in all we are better off without it. This also makes merging
    the lock_dlm module into GFS2 a bit easier.
