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.
