Subject: [PATCH bpf-next v2 2/3] bpf: Rename nfct_bsa to nfct_btf_struct_access
Date: Mon, 19 Sep 2022 13:44:36 -0600	[thread overview]
Message-ID: <07deb5b553790049638758250a118a96be6768d0.1663616584.git.dxu@dxuuu.xyz> (raw)
In-Reply-To: <cover.1663616584.git.dxu@dxuuu.xyz>

The former name was a little hard to guess.
