Subject: [PATCH v2 bpf-next 12/14] bpf: selftests: Rename bictcp to bpf_cubic
Date: Wed, 24 Mar 2021 18:52:40 -0700	[thread overview]
Message-ID: <20210325015240.1550074-1-kafai@fb.com> (raw)
In-Reply-To: <20210325015124.1543397-1-kafai@fb.com>

As a similar chanage in the kernel, this patch gives the proper
name to the bpf cubic.

Acked-by: Andrii Nakryiko <andrii@kernel.org>
