#     Merge tag 'trace-v5.14-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
#     
#     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"
