Hi,

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

http://lkml.kernel.org/r/155248005229.10815.334731901778152247.stgit@devnote2

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,
