From c60f599bcb9bf9256eb87c1c60add55d23f76de3 Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Sun, 17 Apr 2022 11:29:47 -0700 Subject: util/log: Rename qemu_log_lock to qemu_log_trylock MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This function can fail, which makes it more like ftrylockfile or pthread_mutex_trylock than flockfile or pthread_mutex_lock, so rename it. To closer match the other trylock functions, release rcu_read_lock along the failure path, so that qemu_log_unlock need not be called on failure.
