Subject: [PATCH security-next v2 07/26] LSM: Convert security_initcall() into DEFINE_LSM()
Date: Thu, 20 Sep 2018 09:23:19 -0700 [thread overview]
Message-ID: <20180920162338.21060-8-keescook@chromium.org> (raw)
In-Reply-To: <20180920162338.21060-1-keescook@chromium.org>
Instead of using argument-based initializers, switch to defining the
contents of struct lsm_info on a per-LSM basis. This also drops
the final use of the now inaccurate "initcall" naming.
