Subject: [PATCH 3/6] vt: invoke notifier on screen size change
Date: Tue, 8 Jan 2019 22:55:01 -0500 [thread overview]
Message-ID: <20190109035504.8413-4-nicolas.pitre@linaro.org> (raw)
In-Reply-To: <20190109035504.8413-1-nicolas.pitre@linaro.org>
User space using poll() on /dev/vcs devices are not awaken when a
screen size change occurs. Let's fix that.
