Subject: [PATCH] tracing: Have event inject files inc the trace array ref
count

The event inject files add events for a specific trace array. For an instance, if the file is opened and the instance is deleted, reading or writing to the file will cause a use after free.

Up the ref count of the trace_array when a event inject file is opened.
