Subject: notification_send callback takes const event_notifier parameter
X-Git-Tag: v2.13.0-rc1~105
X-Git-Url: http://git.liburcu.org/?a=commitdiff_plain;h=cda77256e7f0cbc8839f9c872b75e77cb1fb7d5c;p=lttng-ust.git

notification_send callback takes const event_notifier parameter

The event parameter of the notification_send callback should be const,
because it should not be modified, only read.
