[PATCH v3 0/2] tracing: Remove trace_printk.h from kernel.h
From: Steven Rostedt
Date: Wed Jun 24 2026 - 04:19:35 EST
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 v2: https://lore.kernel.org/all/20260622130739.375198646@xxxxxxxxxx/
- Update change log in patch 1
- Remove #ifdef DEBUG and always include trace_printk.h in patch 2.
Steven Rostedt (2):
tracing: Move non-trace_printk prototypes into trace_controls.h
tracing: Remove trace_printk.h from kernel.h
