[PATCH RFC bpf-next 0/8] Implement generic bpf_async cb

From: Benjamin Tissoires
Date: Tue May 07 2024 - 09:32:41 EST


This is a RFC, following[0].

It works, still needs some care but this is mainly to see if this will
have a chance to get upsrteamed or if I should rely on struct_ops
instead.

Cheers,
Benjamin
