Subject: [PATCH 0/4] move functions in trace_probe_tmpl.h to trace_probe.c

Below fucntions are defined and implemented in kprobe/eprobe/uprobe
respectively:

1. store_trace_args
2. print_probe_args
3. __get_data_size
4. process_fetch_insn
5. process_fetch_insn_bottom
6. fetch_store_*
7. probe_mem_*

...

They are either identical or similar, which means there is some space to
optimize code organization.

This patchset would like to move them into trace_probe.c as new APIs to
serve those probes and the differences will be merged at the same time.

It improves readability and avoid involving errors while adding a new
feature.

Song Chen (4):
  kernel/trace: Introduce new APIs to process probe arguments
  kernel/trace/kprobe: Use new APIs to process kprobe arguments
  kernel/trace/eprobe: Use new APIs to process eprobe arguments
  kernel/trace/uprobe: Use new APIs to process uprobe arguments
