      tracing/user_events: Replace a seq_printf() call by seq_puts() in user_seq_show()
      fgraph: Use trace_seq_putc() in print_graph_return()

Mykyta Yatsenko (3):
      bpf: Make btf_get_module_btf() and btf_relocate_id() non-static
      tracing: Expose tracepoint BTF ids via tracefs
      selftests/bpf: Add test for tracepoint btf_ids tracefs file

Pengpeng Hou (3):
      tracing: Use __free() for expr_str() buffer
      tracing: Return ERR_PTR() from expr_str()
      tracing: Bound histogram expression strings with seq_buf

Po-Sheng Lin (1):
      tracing: Use strscpy() instead of strcpy() in trace_sched_switch

Samuel Moelius (2):
      tracing: Reject invalid preemptirq_delay_test CPU affinity
