From 5a5f6e78b24881941a75d6b9f1214f0ee0e2f9aa Mon Sep 17 00:00:00 2001 From: Maxime Coquelin Date: Wed, 29 May 2019 15:04:17 +0200 Subject: [PATCH] vhost: do not inline packed and split functions At runtime either packed Tx/Rx functions will always be called, or split Tx/Rx functions will always be called. This patch removes the forced inlining in order to reduce the I-cache pressure.
