From 319951eba0fc412a78a8fe3d2ee5e143cc318c14 Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Tue, 24 Jan 2023 15:40:22 -0500 Subject: [PATCH] SUNRPC: Remove ->xpo_secure_port() There's no need for the cost of this extra virtual function call during every RPC transaction: the RQ_SECURE bit can be set properly in ->xpo_recvfrom() instead.
