Merge tag 'trace-v5.9-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
Pull tracing fixes from Steven Rostedt:
- Check kprobe is enabled before unregistering from ftrace as it isn't
registered when disabled.
- Remove kprobes enabled via command-line that is on init text when
freed.
- Add missing RCU synchronization for ftrace trampoline symbols removed
from kallsyms.
- Free trampoline on error path if ftrace_startup() fails.
- Give more space for the longer PID numbers in trace output.
- Fix a possible double free in the histogram code.
- A couple of fixes that were discovered by sparse.
