Merge tag 'trace-v5.16' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace

Pull tracing updates from Steven Rostedt:

- kprobes: Restructured stack unwinder to show properly on x86 when a
stack dump happens from a kretprobe callback.

- Fix to bootconfig parsing

- Have tracefs allow owner and group permissions by default (only
denying others). There's been pressure to allow non root to tracefs
in a controlled fashion, and using groups is probably the safest.

- Bootconfig memory managament updates.

- Bootconfig clean up to have the tools directory be less dependent on
changes in the kernel tree.

- Allow perf to be traced by function tracer.

- Rewrite of function graph tracer to be a callback from the function
tracer instead of having its own trampoline (this change will happen
on an arch by arch basis, and currently only x86_64 implements it).

- Allow multiple direct trampolines (bpf hooks to functions) be batched
together in one synchronization.

- Allow histogram triggers to add variables that can perform
calculations against the event's fields.

- Use the linker to determine architecture callbacks from the ftrace
trampoline to allow for proper parameter prototypes and prevent
warnings from the compiler.

- Extend histogram triggers to key off of variables.

- Have trace recursion use bit magic to determine preempt context over
if branches.

- Have trace recursion disable preemption as all use cases do anyway.

- Added testing for verification of tracing utilities.

- Various small clean ups and fixes.

selftests/ftrace: Stop tracing while reading the trace file by default

Stop tracing while reading the trace file by default, to prevent
the test results while checking it and to avoid taking a long time
to check the result.
If there is any testcase which wants to test the tracing while reading
the trace file, please override this setting inside the test case.

This also recovers the pause-on-trace when clean it up.

selftests/ftrace: Fix requirement check of README file

The selftest for ftrace checks some features by checking if the README has
text that states the feature is supported by that kernel. Unfortunately,
this check gives false positives because it many not be checked if there's
spaces in the string to check. This is due to the compare between the
required variable with the ":README" string stripped, because neither has
quotes around them.

selftests/ftrace: Add clear_dynamic_events() to test cases

Add a function to remove all dynamic events from the tracing directory. It

removed first. Also add a safety that prevents it from looping infinitely
due to a bug where an event never gets removed.
