From 596b5ef458f903d4362fb3c69967b6d8a23334bd Mon Sep 17 00:00:00 2001 From: Maciej Żenczykowski Date: Tue, 18 Aug 2020 18:07:10 -0700 Subject: net-tun: Eliminate two tun/xdp related function calls from vhost-net MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This provides a minor performance boost by virtue of inlining instead of cross module function calls.
