[PATCH 0/4] tracing/probes: Fixes several bugs

Hi,

Here are a patches to fix some bugs in the probe events and eprobe.
These are found during cleaning up the code. I made these as a split
series because those could be backported. Let me send another
series for cleaning up probe event code.

Thank you,
