From 90f37362d7d2037a47f0c18ab4a26055acbd7b3a Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Sun, 17 Apr 2022 11:29:59 -0700 Subject: [PATCH] util/log: Remove qemu_log_flush MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit All uses flush output immediately before or after qemu_log_unlock. Instead of a separate call, move the flush into qemu_log_unlock.
