Subject: [PATCH 07/10] Allow alsa_t to set scheduling priority and send signal to itself
Date: Fri, 11 Oct 2019 14:24:13 +0200	[thread overview]
Message-ID: <20191011122416.14651-7-bigon@debian.org> (raw)
In-Reply-To: <20191011122416.14651-1-bigon@debian.org>

From: Laurent Bigonville <bigon@bigon.be>

When alsactl is running as a daemon with systemd, it sets its process
priority to be nice to other processes. When stopping the service, it's
signaling to itself that it needs to exit.
