    nfsd: add a new /proc/fs/nfsd/max_connections file · 5b8db00b

    Currently, the maximum number of connections that nfsd will allow
    is based on the number of threads spawned. While this is fine for a
    default, there really isn't a clear relationship between the two.
    
    The number of threads corresponds to the number of concurrent requests
    that we want to allow the server to process at any given time. The
    connection limit corresponds to the maximum number of clients that we
    want to allow the server to handle. These are two entirely different
    quantities.
    
    Break the dependency on increasing threads in order to allow for more
    connections, by adding a new per-net parameter that can be set to a
    non-zero value. The default is still to base it on the number of threads,
    so there should be no behavior change for anyone who doesn't use it.
