[PATCH 5.15.y 0/1] Return EADDRNOTAVAIL when func matches several symbols

[Francis Laniel <flaniel@xxxxxxxxxxxxxxxxxxx>]

Hi!


Applying the upstream patch leaded to compilation error regarding
kallsyms_on_each_match_symbol().
So, I adapted the patch to use kallsyms_on_each_symbol() instead:
root@vm-amd64:~# uname -a
Linux vm-amd64 5.15.136+ #126 SMP Mon Oct 23 15:18:02 EEST 2023 x86_64 GNU/Linux
root@vm-amd64:~# echo 'p:probe/name_show name_show' > /sys/kernel/tracing/kprobe_events
bash: echo: write error: Cannot assign requested address

As I modified the patch, I would like to get some reviews before it lands in
stable.
