Subject: [PATCH 0/4] tracing: Make more function graph tracer options per-instance


Convert the function graph tracer options sleep-time and funcgraph-irqs
into per instance options (as they currently are not consistent in
affecting all instances).

Also make graph-time a top level option only, as it only affects the
function profiler and not the function graph tracer itself.

Clean up the function graph tracer set_flags() to use a switch instead
of a bunch of if statements.

Steven Rostedt (4):
      tracing: Have function graph tracer option funcgraph-irqs be per instance
      tracing: Move graph-time out of function graph options
      tracing: Have function graph tracer option sleep-time be per instance
      tracing: Convert function graph set_flags() to use a switch() statement
