sunrpc: Save remote presentation address in svc_xprt for trace events
TP_printk defines a format string that is passed to user space for converting raw trace event records to something human-readable. My user space's printf (Oracle Linux 7), however, does not have a %pI format specifier. The result is that what is supposed to be an IP address in the output of "trace-cmd report" is just a string that says the field couldn't be displayed. To fix this, adopt the same approach as the client: maintain a pre- formated presentation address for occasions when %pI is not available. The location of the trace_svc_send trace point is adjusted so that rqst->rq_xprt is not NULL when the trace event is recorded. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: J.
