Subject: [PATCH v3 0/4] tracing/probes: Fix bugs in process_fetch_insn

Hi,

Here are the 3rd version of fix bugs in process_fetch_insn_*().
The previous version is here;

https://lore.kernel.org/all/168873724526.2687993.15242662075324919195.stgit@mhiramat.roam.corp.google.com/

[3/4] is updated to move FAULT_STRING macro to trace_probe.h
and use it in trace_probe.c instead of "(fault)".

Thank you,

---

      tracing/probes: Fix to avoid double count of the string length on the array
      tracing/probes: Fix not to count error code to total length
      Revert "tracing: Add "(fault)" name injection to kernel probes"
      tracing/probes: Fix to record 0-length data_loc in fetch_store_string*() if fails
