[PATCH v3 0/6] trace-cmd: Use BTF to show the arguments for function tracers

From: "Steven Rostedt (Google)" <[email protected]>


Have trace-cmd use the new BTF parsing to show the arguments of function
tracing.

Changes since v2: https://lore.kernel.org/all/[email protected]

- Fixed tracecmd_append_btf_file() exiting out early when btf file doesn't
  exist. That would cause the offset to be incorrect and the next write to
  the trace.dat file would corrupt it. This happened with trace-cmd extract.

Steven Rostedt (Google) (6):
  libtracecmd: Remove "compress" parameter from save_string_section()
  libtracecmd: Remove "compress" parameter from tcmd_out_compress*() functions
  libtracecmd: Add write_compress_section_header() for writing compress sections
  trace-cmd record / report: Record BTF file if function arguments are recorded
  libtracecmd: Add printing of arguments for function graph tracer
  trace-cmd documenatation: Update the trace.dat man page for BTF_FILE
