From e18e157bb5c8c1cd8a9ba25acfdcf4f3035836f4 Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Wed, 19 Jul 2023 14:31:09 -0400 Subject: SUNRPC: Send RPC message on TCP with a single sock_sendmsg() call There is now enough infrastructure in place to combine the stream record marker into the biovec array used to send each outgoing RPC message on TCP. The whole message can be more efficiently sent with a single call to sock_sendmsg() using a bio_vec iterator. Note that this also helps with RPC-with-TLS: the TLS implementation can now clearly see where the upper layer message boundaries are. Before, it would send each component of the xdr_buf (record marker, head, page payload, tail) in separate TLS records.
