Subject: [PATCH 20/90] LSM: Use lsm_export in security_task_getsecid
Date: Thu, 18 Apr 2019 17:45:07 -0700
Message-ID: <20190419004617.64627-21-casey@schaufler-ca.com> (raw)
In-Reply-To: <20190419004617.64627-1-casey@schaufler-ca.com>

Convert security_task_getsecid to use the lsm_export structure
instead of a u32 secid. There is some scaffolding involved
that will be removed when the related data is updated.
