Merge tag 'trace-v6.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull tracing fixes from Steven Rostedt:
- Do not allow histogram values to have modifies. They can cause a NULL
pointer dereference if they do.
- Warn if hist_field_name() is passed a NULL. Prevent the NULL pointer
dereference mentioned above.
- Fix invalid address look up race in lookup_rec()
- Define ftrace_stub_graph conditionally to prevent linker errors
- Always check if RCU is watching at all tracepoint locations
* tag 'trace-v6.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace:
tracing: Make tracepoint lockdep check actually test something
ftrace,kcfi: Define ftrace_stub_graph conditionally
ftrace: Fix invalid address access in lookup_rec() when index is 0
tracing: Check field value in hist_field_name()
tracing: Do not let histogram values have some modifiers
