Subject: [PATCH RFC HID 0/7] Use the new __s_async for HID-BPF

This is not meant to be applied as of now.

This is just to show what I meant for [0].

And of course, this doesn't even compile because you need [0] to be
applied and the branch for-6.10/hid-bpf on the hid tree.

The purpose is to remove the bpf_tail_call from the preloaded bpf at
boot time.

Cheers,
Benjamin
