Trond Myklebust d21287d8a4 SUNRPC: Ensure we flush any closed sockets before xs_xprt_free() ... commit f00432063d upstream. We must ensure that all sockets are closed before we call xprt_free() and release the reference to the net namespace. The problem is that calling fput() will defer closing the socket until delayed_fput() gets called. Let's fix the situation by allowing rpciod and the transport teardown code (which runs on the system wq) to call __fput_sync(), and directly close the socket.
