Merge tag 'trace-v5.11-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
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"
