[PATCH v3 0/3] tracing: probeevent: Fix probe argument parser and handler

[Masami Hiramatsu <mhiramat@kernel.org>]

Hi,

Here is the 3rd version of series to fix several bugs in probe event
argument parser and handler routines.

In this version I updated patch [1/3] according to Steve's comment.


I got 2 issues reported by Andreas, see
https://www.mail-archive.com/linux-kernel@vger.kernel.org/msg1899098.html

One issue is already fixed by Andreas (Thanks!) but $comm handling
issue still exists on uprobe event. [1/3] fixes it.
And I found other issues around that, [2/3] is just a trivial cleanup,
[3/3] fixes $comm type issue which occurs not only uprobe events but
also on kprobe events. Anyway, after this series applied, $comm must
be "string" type and not be an array.

Thank you,
