Subject: [PATCH security-next v5 06/30] vmlinux.lds.h: Move LSM_TABLE into INIT_DATA
Date: Wed, 10 Oct 2018 17:18:22 -0700	[thread overview]
Message-ID: <20181011001846.30964-7-keescook@chromium.org> (raw)
In-Reply-To: <20181011001846.30964-1-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.
