While that doesn't matter in case of the Lockdown LSM,\nit causes trouble with the SELinux's lockdown hook implementation.\n\nSELinux implements the locked_down hook with a check whether the current\ntask's type has the corresponding \"lockdown\" class permission\n(\"integrity\" or \"confidentiality\") allowed in the policy. This means\nthat calling the hook when the access control decision would be ignored\ngenerates a bogus permission check and audit record.\n\nFix this by checking sample_type first and only calling the hook when\nits result would be honored."
