Description

We would like to see a higher time resolution in ptlrpc_lprocfs_svc_req_history_show output.

Here we see it is only printing up to a second.

seq_printf(s, LPD64":%s:%s:x"LPU64":%d:%s:%ld:%lds(%+lds) ",
                           req->rq_history_seq, libcfs_nid2str(req->rq_self),
                           libcfs_id2str(req->rq_peer), req->rq_xid,
                           req->rq_reqlen, ptlrpc_rqphase2str(req),
                           req->rq_arrival_time.tv_sec,
                           req->rq_sent - req->rq_arrival_time.tv_sec,
                           req->rq_sent - req->rq_deadline);
