RPC tasks on the backchannel never invoke xprt_complete_rqst(), so there is no way to report their tk_status at completion. Also, any RPC task that exits via rpc_exit_task() before it is replied to will also disappear without a trace. Introduce a trace point that is symmetrical with rpc_task_begin that captures the termination status of each RPC task. Sample trace output for callback requests initiated on the server: kworker/u8:12-448 [003] 127.025240: rpc_task_end: task:50@3 flags=ASYNC|DYNAMIC|SOFT|SOFTCONN|SENT runstate=RUNNING|ACTIVE status=0 action=rpc_exit_task kworker/u8:12-448 [002] 127.567310: rpc_task_end: task:51@3 flags=ASYNC|DYNAMIC|SOFT|SOFTCONN|SENT runstate=RUNNING|ACTIVE status=0 action=rpc_exit_task kworker/u8:12-448 [001] 130.506817: rpc_task_end: task:52@3 flags=ASYNC|DYNAMIC|SOFT|SOFTCONN|SENT runstate=RUNNING|ACTIVE status=0 action=rpc_exit_task Odd, though, that I never see trace_rpc_task_complete, either in the forward or backchannel.
