    Subject[PATCH 3.4 019/172] vt: provide notifications on selection changes
    Date
    From: Nicolas Pitre <nicolas.pitre@linaro.org>

    3.4.108-rc1 review patch. If anyone has any objections, please let me know.

    ------------------


    commit 19e3ae6b4f07a87822c1c9e7ed99d31860e701af upstream.

    The vcs device's poll/fasync support relies on the vt notifier to signal
    changes to the screen content. Notifier invocations were missing for
    changes that comes through the selection interface though. Fix that.

    Tested with BRLTTY 5.2.
