Subject: [PATCH security-next v4 11/32] LSM: Introduce LSM_FLAG_LEGACY_MAJOR
Date: Mon,  1 Oct 2018 17:54:44 -0700	[thread overview]
Message-ID: <20181002005505.6112-12-keescook@chromium.org> (raw)
Message-ID: <20181002005444.3Ur-8y5RiY6GPIXvUUkc79__I7PAjG6j7aFA1rN0QLs@z> (raw)
In-Reply-To: <20181002005505.6112-1-keescook@chromium.org>

This adds a flag for the current "major" LSMs to distinguish them when
we have a universal method for ordering all LSMs. It's called "legacy"
since the distinction of "major" will go away in the blob-sharing world.
