Subject: [PATCH v4 bpf-next 01/10] libbpf: add "tc" SEC_DEF which is a better name for "classifier"
Date: Tue, 28 Sep 2021 09:19:37 -0700 [thread overview]
Message-ID: <20210928161946.2512801-2-andrii@kernel.org> (raw)
In-Reply-To: <20210928161946.2512801-1-andrii@kernel.org>
As argued in [0], add "tc" ELF section definition for SCHED_CLS BPF
program type. "classifier" is a misleading terminology and should be
migrated away from.
