Merge tag 'trace-tools-v7.3' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace

Pull RTLA updates from Steven Rostedt:

- Extend support for unsetting CLI options

libsubcmd auto-generates "--no-<option>" to unset options, provided
the option callback supports it. Implement this for RTLA CLI beyond
boolean options, and document the few exceptions that are left out.

- Test all tracer options in runtime tests

Verify that RTLA sets osnoise/timerlat options correctly by reading
them from tracefs during runtime tests.

- Improve range validation for option arguments

Make CLI range validation consistent with the kernel limits and unify
implementation and error messages between options.

- Improve invalid option argument parsing

Consistently reject invalid values for numeric option arguments with
a unified error message for all options.

rtla/tests: Test all tracer options in runtime tests

Currently, runtime tests only test the osnoise period option
(-p/--period of rtla-osnoise tools, backed by
/sys/kernel/tracing/osnoise/period_us)

rtla/tests: Test all tracer options in runtime tests

Currently, runtime tests only test the osnoise period option
(-p/--period of rtla-osnoise tools, backed by
/sys/kernel/tracing/osnoise/period_us), using the
check_with_osnoise_options function together with a hack relying on long
period (pre-set) timing out if RTLA fails to reset it to the default
value.

Extend tracer option testing to all options used by RTLA; test both RTLA
setting the default option by pre-setting the tracer to a different
value and user-requested value.

The tests are done using a script that reads the tracer values inside an
--on-threshold action, like existing tests for runtime behavior already
do. check_with_osnoise_option is modified to support grep filters, so
that it can be used together with the script pattern.
