    Subject[PATCH v2 0/9] tracing vs rcu vs nmi
    Hi all,

    These here patches are the result of Mathieu and Steve trying to get commit
    865e63b04e9b2 ("tracing: Add back in rcu_irq_enter/exit_irqson() for rcuidle
    tracepoints") reverted again.

    One of the things discovered is that tracing MUST NOT happen before nmi_enter()
    or after nmi_exit(). Audit results of the previous version are still valid.

    Changes since -v1:

    - Added tags
    - Changed #4; changed nmi_enter() to use __preempt_count_add() vs
    marking preempt_count_add() notrace.
    - Changed #5; confusion on which functions are notrace due to Makefile
    - Added #9; remove limitation on the perf-function-trace coupling
