[PATCH v2 0/2] tracing: Remove trace_printk.h from kernel.h

[Steven Rostedt <rostedt@kernel.org>]

Remove trace_printk.h by creating a trace_controls.h for those places that
need access to tracing prototypes like tracing_off() and for the places that
need trace_printk() directly, to have it included directly.

Changse since v1: https://lore.kernel.org/all/20260621093430.264983361@kernel.org/

- Create a trace_controls.h header to move the prototypes into and not
  include it back into kernel.h

- Just remove trace_printk.h from kernel.h with no alternative to keep the
  previous behavior.
