    sunrpc: create a new dummy pipe for gssd to hold open · 4b9a445e
    Jeff Layton authored
    rpc.gssd will naturally hold open any pipe named */clnt*/gssd that shows
    up under rpc_pipefs. That behavior gives us a reliable mechanism to tell
    whether it's actually running or not.
    
    Create a new toplevel "gssd" directory in rpc_pipefs when it's mounted.
    Under that directory create another directory called "clntXX", and then
    within that a pipe called "gssd".
    
    We'll never send an upcall along that pipe, and any downcall written to
    it will just return -EINVAL.
