Subject: [PATCH hid v12 00/15] Introduce eBPF support for HID devices
Date: Thu,  3 Nov 2022 16:57:41 +0100	[thread overview]
Message-ID: <20221103155756.687789-1-benjamin.tissoires@redhat.com> (raw)

Hi,

and here comes the v12 of the HID-BPF series.

Again, for a full explanation of HID-BPF, please refer to the last patch
in this series (15/15).

This revision contains most notably few fixes from the various kernel CI
bots. I also took Alexei's review into account, and we do not pollute
tools/include with useless hid headers.

I also removed most of the last checkpatch complains about adding
external kfunc declarations in C files. And this led me to also show in
samples/ how we can link together 2 BPF object files. Impressive how
easy it is :)

Cheers,
Benjamin
