#1628597 — [for-next][PATCH 30/33] tracing/ftrace: Allow instances to have their own function probes

From: "Steven Rostedt (VMware)" <rostedt@goodmis.org>

Pass around the local trace_array that is the descriptor for tracing
instances, when enabling and disabling probes. This by default sets the
enable/disable of event probe triggers to work with instances.

The other probes will need some more work to get them working with
instances.
