From 0a6ff58edbfb26469a095ab964095506352fc960 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Tue, 24 Aug 2021 11:38:17 -0400 Subject: SUNRPC: Simplify socket shutdown when not reusing TCP ports If we're not required to reuse the TCP port, then we can just immediately close the socket, and leave the cleanup details to the TCP layer.
