Subject: [PATCH bpf-next] bpftool: fix C++ additions to skeleton
Date: Wed, 16 Feb 2022 15:35:40 -0800	[thread overview]
Message-ID: <20220216233540.216642-1-andrii@kernel.org> (raw)

Mark C++-specific T::open() and other methods as static inline to avoid
symbol redefinition when multiple files use the same skeleton header in
an application.

Fixes: bb8ffe61ea45 ("bpftool: Add C++-specific open/load/etc skeleton wrappers")
Signed-off-by: Andrii Nakryiko <andrii@kernel.org>
