Subject: [PATCH v2 0/4] perf-probe: Fix GNU IFUNC probe issue etc.

Hi,

Here are the v2 patches to fix some issues of probing on GNU IFUNC,
duplicated symbols, and memory leak, which were reported by Andi.
V1 is here:

 https://lkml.kernel.org/r/159428201109.56570.3802208017109058146.stgit@devnote2

In this version, I've added Srikar's reviewed-by and Andi's Tested-by (Thanks
Srikar and Andi!) and fix some messages and code according to the comment.

Thank you,
