[PATCH 5.4.y 0/1] Return EADDRNOTAVAIL when func matches several symbols during kprobe creation

[Francis Laniel <flaniel@xxxxxxxxxxxxxxxxxxx>]

Hi.


There was problem to apply upstream patch on kernel 5.4.

I adapted the patch and came up with the attached one, it was tested and
validated:
root@vm-amd64:~# uname -a
Linux vm-amd64 5.4.258+ #121 SMP Mon Oct 23 14:22:43 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 had to modify the patch, I would like to get reviews before getting it
merged in stable.
