    [PATCH] PATCH 12/16: NFSD: TCP: Close idle TCP connections · cbf593fc
    Neil Brown authored
    Close idle rpc/tcp sockets
    
    We split the list of sv_allsocks into two, one
    of permanent sockets (udp, tcp listener) and one
    of temporary sockets (tcp data).
    
    Whenever we complete a successful receive on a temp socket,
    it gets pushed to the end of the list.
    
    Whenever a thread wants to do something, it first checks if
    the oldest temp socket has not has a receive for 6 mintutes
    (should possibly be configurable).  It so, we simulate
    a close.
    
    Finally we make sure that threads wake up every few minutes
    so that if the server is completely idle, all temp
    sockets will get closed.
