Merge tag 'trace-v5.12-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
Pull tracing fix from Steven Rostedt: "Fix tp_printk command line and trace events Masami added a wrapper to be able to unhash trace event pointers as they are only read by root anyway, and they can also be extracted by the raw trace data buffers. But this wrapper utilized the iterator to have a temporary buffer to manipulate the text with. tp_printk is a kernel command line option that will send the trace output of a trace event to the console on boot up (useful when the system crashes before finishing the boot). But the code used the same wrapper that Masami added, and its iterator did not have a buffer, and this caused the system to crash. Have the wrapper just print the trace event normally if the iterator has no temporary buffer" * tag 'trace-v5.12-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: tracing: Fix checking event hash pointer logic when tp_printk is enabled
