Pull tracing fix from Steven Rostedt: "Limit the shooting in the foot of tp_printk The "tp_printk" option redirects the trace event output to printk at boot up. This is useful when a machine crashes before boot where the trace events can not be retrieved by the in kernel ring buffer. But it can be "dangerous" because trace events can be located in high frequency locations such as interrupts and the scheduler, where a printk can slow it down that it live locks the machine (because by the time the printk finishes, the next event is triggered). Thus tp_printk must be used with care. It was discovered that the filter logic to trace events does not apply to the tp_printk events. This can cause a surprise and live lock when the user expects it to be filtered to limit the amount of events printed to the console when in fact it still prints everything" * tag 'trace-v5.14-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: tracing: Apply trace filters on all output channels
