#     
#     Pull tracing fix from Steven Rostedt:
#      "Blacklist properly on all archs.
#     
#       The code to blacklist notrace functions for kprobes was not using the
#       right kconfig option, which caused some archs (powerpc) to possibly
#       not blacklist them"
#     
#     * tag 'trace-v5.11-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace:
#       tracing/kprobes: Do the notrace functions check without kprobes on ftrace
