From: Trond Myklebust Date: Thu, 13 May 2010 16:51:49 +0000 (-0400) Subject: SUNRPC: Move the task->tk_bytes_sent and tk_rtt to struct rpc_rqst X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=d60dbb20a74c2cfa142be0a34dac3c6547ea086c;p=openwrt%2Fstaging%2Fblogic.git SUNRPC: Move the task->tk_bytes_sent and tk_rtt to struct rpc_rqst It seems strange to maintain stats for bytes_sent in one structure, and bytes received in another. Try to assemble all the RPC request-related stats in struct rpc_rqst Signed-off-by: Trond Myklebust --- diff --git a/include/linux/sunrpc/sched.h b/include/linux/sunrpc/sched.h index 76720d262ef2..46ebef1788c6 100644 --- a/include/linux/sunrpc/sched.h +++ b/include/linux/sunrpc/sched.h @@ -80,9 +80,7 @@ struct rpc_task { } u; unsigned short tk_timeouts; /* maj timeouts */ - size_t tk_bytes_sent; /* total bytes sent */ - ktime_t tk_start, /* RPC task init timestamp */ - tk_rtt; /* round-trip time */ + ktime_t tk_start; /* RPC task init timestamp */ pid_t tk_owner; /* Process id for batching tasks */ unsigned char tk_priority : 2;/* Task priority */ diff --git a/include/linux/sunrpc/xprt.h b/include/linux/sunrpc/xprt.h index f8851861b744..b51470302399 100644 --- a/include/linux/sunrpc/xprt.h +++ b/include/linux/sunrpc/xprt.h @@ -66,8 +66,6 @@ struct rpc_rqst { struct rpc_task * rq_task; /* RPC task data */ __be32 rq_xid; /* request XID */ int rq_cong; /* has incremented xprt->cong */ - int rq_reply_bytes_recvd; /* number of reply */ - /* bytes received */ u32 rq_seqno; /* gss seq no. used on req. */ int rq_enc_pages_num; struct page **rq_enc_pages; /* scratch pages for use by @@ -78,12 +76,16 @@ struct rpc_rqst { __u32 * rq_buffer; /* XDR encode buffer */ size_t rq_callsize, rq_rcvsize; + size_t rq_xmit_bytes_sent; /* total bytes sent */ + size_t rq_reply_bytes_recvd; /* total reply bytes */ + /* received */ struct xdr_buf rq_private_buf; /* The receive buffer * used in the softirq. */ unsigned long rq_majortimeo; /* major timeout alarm */ unsigned long rq_timeout; /* Current timeout value */ + ktime_t rq_rtt; /* round-trip time */ unsigned int rq_retries; /* # of retries */ unsigned int rq_connect_cookie; /* A cookie used to track the diff --git a/net/sunrpc/stats.c b/net/sunrpc/stats.c index aacd95f0dce5..ea1046f3f9a3 100644 --- a/net/sunrpc/stats.c +++ b/net/sunrpc/stats.c @@ -156,13 +156,13 @@ void rpc_count_iostats(struct rpc_task *task) op_metrics->om_ntrans += req->rq_ntrans; op_metrics->om_timeouts += task->tk_timeouts; - op_metrics->om_bytes_sent += task->tk_bytes_sent; + op_metrics->om_bytes_sent += req->rq_xmit_bytes_sent; op_metrics->om_bytes_recv += req->rq_reply_bytes_recvd; delta = ktime_sub(req->rq_xtime, task->tk_start); op_metrics->om_queue = ktime_add(op_metrics->om_queue, delta); - op_metrics->om_rtt = ktime_add(op_metrics->om_rtt, task->tk_rtt); + op_metrics->om_rtt = ktime_add(op_metrics->om_rtt, req->rq_rtt); delta = ktime_sub(ktime_get(), task->tk_start); op_metrics->om_execute = ktime_add(op_metrics->om_execute, delta); diff --git a/net/sunrpc/xprt.c b/net/sunrpc/xprt.c index 8986b1b82862..65fe2e4e7cbf 100644 --- a/net/sunrpc/xprt.c +++ b/net/sunrpc/xprt.c @@ -780,7 +780,7 @@ static void xprt_update_rtt(struct rpc_task *task) struct rpc_rqst *req = task->tk_rqstp; struct rpc_rtt *rtt = task->tk_client->cl_rtt; unsigned timer = task->tk_msg.rpc_proc->p_timer; - long m = usecs_to_jiffies(ktime_to_us(task->tk_rtt)); + long m = usecs_to_jiffies(ktime_to_us(req->rq_rtt)); if (timer) { if (req->rq_ntrans == 1) @@ -805,7 +805,7 @@ void xprt_complete_rqst(struct rpc_task *task, int copied) task->tk_pid, ntohl(req->rq_xid), copied); xprt->stat.recvs++; - task->tk_rtt = ktime_sub(ktime_get(), req->rq_xtime); + req->rq_rtt = ktime_sub(ktime_get(), req->rq_xtime); if (xprt->ops->timer != NULL) xprt_update_rtt(task); diff --git a/net/sunrpc/xprtrdma/transport.c b/net/sunrpc/xprtrdma/transport.c index 3f3b38c5642f..a85e866a77f7 100644 --- a/net/sunrpc/xprtrdma/transport.c +++ b/net/sunrpc/xprtrdma/transport.c @@ -674,7 +674,7 @@ xprt_rdma_send_request(struct rpc_task *task) if (rpcrdma_ep_post(&r_xprt->rx_ia, &r_xprt->rx_ep, req)) goto drop_connection; - task->tk_bytes_sent += rqst->rq_snd_buf.len; + rqst->rq_xmit_bytes_sent += rqst->rq_snd_buf.len; rqst->rq_bytes_sent = 0; return 0; diff --git a/net/sunrpc/xprtsock.c b/net/sunrpc/xprtsock.c index beefa7a3a90e..02fc7f04dd17 100644 --- a/net/sunrpc/xprtsock.c +++ b/net/sunrpc/xprtsock.c @@ -528,7 +528,7 @@ static int xs_udp_send_request(struct rpc_task *task) xdr->len - req->rq_bytes_sent, status); if (status >= 0) { - task->tk_bytes_sent += status; + req->rq_xmit_bytes_sent += status; if (status >= req->rq_slen) return 0; /* Still some bytes left; set up for a retry later. */ @@ -624,7 +624,7 @@ static int xs_tcp_send_request(struct rpc_task *task) /* If we've sent the entire packet, immediately * reset the count of bytes sent. */ req->rq_bytes_sent += status; - task->tk_bytes_sent += status; + req->rq_xmit_bytes_sent += status; if (likely(req->rq_bytes_sent >= req->rq_slen)) { req->rq_bytes_sent = 0; return 0;
