Merge tag 'trace-v6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull tracing updates from Steven Rostedt: - Add options to the osnoise tracer: - 'panic_on_stop' option that panics the kernel if osnoise is greater than some user defined threshold. - 'preempt' option, to test noise while preemption is disabled - 'irq' option, to test noise when interrupts are disabled - Add .percent and .graph suffix to histograms to give different outputs - Add nohitcount to disable showing hitcount in histogram output - Add new __cpumask() to trace event fields to annotate that a unsigned long array is a cpumask to user space and should be treated as one. - Add trace_trigger kernel command line parameter to enable trace event triggers at boot up. Useful to trace stack traces, disable tracing and take snapshots. - Fix x86/kmmio mmio tracer to work with the updates to lockdep - Unify the panic and die notifiers - Add back ftrace_expect reference that is used to extract more information in the ftrace_bug() code. - Have trigger filter parsing errors show up in the tracing error log. - Updated MAINTAINERS file to add kernel tracing mailing list and patchwork info - Use IDA to keep track of event type numbers. - And minor fixes and clean ups * tag 'trace-v6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: (44 commits) tracing: Fix cpumask() example typo tracing: Improve panic/die notifiers ftrace: Prevent RCU stall on PREEMPT_VOLUNTARY kernels tracing: Do not synchronize freeing of trigger filter on boot up tracing: Remove pointer (asterisk) and brackets from cpumask_t field tracing: Have trigger filter parsing errors show up in error_log x86/mm/kmmio: Remove redundant preempt_disable() tracing: Fix infinite loop in tracing_read_pipe on overflowed print_trace_line Documentation/osnoise: Add osnoise/options documentation tracing/osnoise: Add preempt and/or irq disabled options tracing/osnoise: Add PANIC_ON_STOP option Documentation/osnoise: Escape underscore of NO_ prefix tracing: Fix some checker warnings tracing/osnoise: Make osnoise_options static tracing: remove unnecessary trace_trigger ifdef ring-buffer: Handle resize in early boot up tracing/hist: Fix issue of losting command info in error_log tracing: Fix issue of missing one synthetic field tracing/hist: Fix out-of-bound write on 'action_data.var_ref_idx' tracing/hist: Fix wrong return value in parse_action_params() ...
