Subject: [PATCH security-next v3 06/29] vmlinux.lds.h: Move LSM_TABLE into INIT_DATA
Date: Mon, 24 Sep 2018 17:18:09 -0700 [thread overview]
Message-ID: <20180925001832.18322-7-keescook@chromium.org> (raw)
In-Reply-To: <20180925001832.18322-1-keescook@chromium.org>
Since the struct lsm_info table is not an initcall, we can just move it
into INIT_DATA like all the other tables.
