From 2eb2b93581813b74c7174961126f6ec38eadb5a7 Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Wed, 19 Jul 2023 14:31:03 -0400 Subject: SUNRPC: Convert svc_tcp_sendmsg to use bio_vecs directly Add a helper to convert a whole xdr_buf directly into an array of bio_vecs, then send this array instead of iterating piecemeal over the xdr_buf containing the outbound RPC message.
