Subject: [PATCH v5 0/5] tracing/probes: Fix bugs in process_fetch_insn

Hi,

Here are the 5th version of fix bugs in process_fetch_insn_*().
The previous version is here;

https://lore.kernel.org/all/168904147563.2908673.18054267804278861545.stgit@mhiramat.roam.corp.google.com/

In this version I added a bugfix to update dynamic data counter only
if the fetcharg uses it [3/5] and update [5/5] to move out the arg->dynamic
check out from unlikely() macro and use likely() macro correctly for
non-error case.

Thank you,

---
