Subject: [RFC PATCH bpf-next 0/2] Add prog_kfunc feature probe
Date: Thu, 23 Jan 2025 00:55:21 +0800 [thread overview]
Message-ID: <20250122165523.1033775-1-chen.dylane@gmail.com> (raw)
More and more kfunc functions are being added to the kernel.
Different prog types have different restrictions when using kfunc.
Therefore, prog_kfunc probe is added to check whether it is supported,
and the use of this api will be added to bpftool later.
