Subject: [PATCH bpf-next v3 3/6] bpf: Correct the comment about insn_to_jit_off
Date: Mon, 30 May 2022 17:28:12 +0800 [thread overview]
Message-ID: <20220530092815.1112406-4-pulehui@huawei.com> (raw)
In-Reply-To: <20220530092815.1112406-1-pulehui@huawei.com>
The insn_to_jit_off passed to bpf_prog_fill_jited_linfo should be
the first byte of the next instruction, or the byte off to the end
of the current instruction.
