Subject: [RFC 10/31] objtool: Use 'struct elf' in elf macros
Date: Mon, 2 Sep 2024 20:59:53 -0700 [thread overview]
Message-ID: <d9eb524fc9c0f35356d956ce5a2cea4cd8e8714e.1725334260.git.jpoimboe@kernel.org> (raw)
In-Reply-To: <cover.1725334260.git.jpoimboe@kernel.org>
'struct objtool_file' is specific to the check code and doesn't belong
in the elf code.
