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
