Subject: [PATCH v2 25/26] modpost: simplify the ->is_static initialization
Date: Sun, 1 May 2022 17:40:31 +0900 [thread overview]
Message-ID: <20220501084032.1025918-26-masahiroy@kernel.org> (raw)
In-Reply-To: <20220501084032.1025918-1-masahiroy@kernel.org>
->is_static is set to true at allocation, then to false if the symbol
comes from the dump file.
It is simpler to use !mod->from_dump as the init value.
