Chuck Lever 5f39d2713b SUNRPC: Move the svc_xdr_recvfrom tracepoint again ... Commit 156708adf2 ("SUNRPC: Move the svc_xdr_recvfrom() tracepoint") tried to capture the correct XID in the trace record, but this line in svc_recv: rqstp->rq_xid = svc_getu32(&rqstp->rq_arg.head[0]); alters the size of rq_arg.head[0].iov_len. The tracepoint records the correct XID but an incorrect value for the length of the xdr_buf's head. To keep the trace callsites simple, I've created two trace classes. One assumes the xdr_buf contains a full RPC message, and the XID can be extracted from it. The other assumes the contents of the xdr_buf are arbitrary, and the xid will be provided by the caller. Currently there is only one user of each class, but I expect we will need a few more tracepoints using each class as time goes on.
