Subject: [PATCH 25/29] modpost: remove mod->skip struct member
Date: Sun, 17 May 2020 18:48:55 +0900	[thread overview]
Message-ID: <20200517094859.2376211-26-masahiroy@kernel.org> (raw)
In-Reply-To: <20200517094859.2376211-1-masahiroy@kernel.org>

The meaning of 'skip' is obscure since it does not explain
"what to skip".

mod->skip is set when it is vmlinux or the module info came from
a dump file.

So, mod->skip is equivalent to (mod->is_vmlinux || mod->from_dump).

For the check in write_namespace_deps_files(), mod->is_vmlinux is
unneeded because the -d option is not passed in the first pass of
modpost.
