[RFC PATCH v2 0/7] tracing: Use common error_log with probe events


Here is the 2nd version of using common error_log  with probe events.
Previous version is here.


In this version, I've updated some error messages according to
Steve's comment, adjust some error position, and update testcase
to simplify a bit.

 - [4/7]: Update error message according to Steve's comment (Thanks!)
 - [6/7]: Update error message, adjust error positions, and add uprobe errors
 - [7/7]: Specify error position in command string by "^".
          Clear error_log right before writing command.
          Add uprobe syntax error checker

Thank you,
