Subject: [PATCH v5 01/38] LSM: Introduce LSM_FLAG_LEGACY_MAJOR
Date: Mon, 26 Nov 2018 15:26:46 -0800 [thread overview]
Message-ID: <ecb10f5c-7bbd-fb2e-4148-63290bc9a7ff@schaufler-ca.com> (raw)
In-Reply-To: <50db058a-7dde-441b-a7f9-f6837fe8b69f@schaufler-ca.com>
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.
