It seems that the perf was depending on the rcuidle # tracepoints to make RCU watch when it wasn't. # # The real fix will be to have perf use SRCU instead of depending on # RCU watching, but that can't be done until SRCU is safe to use in # NMI context (Paul's working on that). # # - The second bug fix is for a bug that's been periodically making my # tests fail randomly for some time. I haven't had time to track it # down, but finally have. It has to do with stressing NMIs (via perf) # while enabling or disabling ftrace function handling with lockdep # enabled. # # If an interrupt happens and just as it returns, it sets lockdep # back to "interrupts enabled" but before it returns an NMI is # triggered, and if this happens while printk_nmi_enter has a # breakpoint attached to it (because ftrace is converting it to or # from nop to call fentry), the breakpoint trap also calls into # lockdep, and since returning from the NMI to a interrupt handler, # interrupts were disabled when the NMI went off, lockdep keeps its # state as interrupts disabled when it returns back from the # interrupt handler where interrupts are enabled. # # This causes lockdep_assert_irqs_enabled() to trigger a false # positive" # # * tag 'trace-v4.19-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: # printk/tracing: Do not trace printk_nmi_enter() # tracing: Add back in rcu_irq_enter/exit_irqson() for rcuidle tracepoints #
