Merge tag 'trace-rv-6.19' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace

Pull runtime verifier updates from Steven Rostedt:

- Adapt the ftracetest script to be run from a different folder

This uses the already existing OPT_TEST_DIR but extends it further to
run independent tests, then add an --rv flag to allow using the
script for testing RV (mostly) independently on ftrace.

- Add basic RV selftests in selftests/verification for more validations

Add more validations for available/enabled monitors and reactors.
This could have caught the bug introducing kernel panic solved above.
Tests use ftracetest.

- Convert react() function in reactor to use va_list directly

Use a central helper to handle the variadic arguments. Clean up
macros and mark functions as static.

- Add lockdep annotations to reactors to have lockdep complain of
errors

If the reactors are called from improper context. Useful to develop
new reactors. This highlights a warning in the panic reactor that is
related to the printk subsystem and not to RV.

- Convert core RV code to use lock guards and __free helpers

This completely removes goto statements.

- Fix compilation if !CONFIG_RV_REACTORS

Fix the warning by keeping LTL monitor variable as always static.

selftests/verification: Add initial RV tests

Add a series of tests to validate the RV tracefs API and basic
functionality.

* available monitors:
Check that all monitors (from the monitors folder) appear as
available and have a description. Works with nested monitors.

* enable/disable:
Enable and disable all monitors and validate both the enabled file
and the enabled_monitors. Check that enabling container monitors
enables all nested monitors.

* reactors:
Set all reactors and validate the setting, also for nested monitors.

* wwnr with printk:
wwnr is broken on purpose, run it with a load and check that the
printk reactor works. Also validate disabling reacting_on or
monitoring_on prevents reactions.

These tests use the ftracetest suite.
