Subject: [PATCH bpf-next 01/17] bpftool: support dumping BTF VAR's "extern" linkage
Date: Wed, 14 Apr 2021 13:01:30 -0700 [thread overview]
Message-ID: <20210414200146.2663044-2-andrii@kernel.org> (raw)
In-Reply-To: <20210414200146.2663044-1-andrii@kernel.org>
Add dumping of "extern" linkage for BTF VAR kind. Also shorten
"global-allocated" to "global" to be in line with FUNC's "global".
Signed-off-by: Andrii Nakryiko <andrii@kernel.org>
