+// KeyctlRestrictKeyring implements the KEYCTL_RESTRICT_KEYRING command. This
+// command limits the set of keys that can be linked to the keyring, regardless
+// of keyring permissions. The command requires the "setattr" permission.
+//
+// When called with an empty keyType the command locks the keyring, preventing
+// any further keys from being linked to the keyring.
+//
+// The "asymmetric" keyType defines restrictions requiring key payloads to be
+// DER encoded X.509 certificates signed by keys in another keyring. Restrictions
+// for "asymmetric" include "builtin_trusted", "builtin_and_secondary_trusted",
+// "key_or_keyring:<key>", and "key_or_keyring:<key>:chain".
+//
+// As of Linux 4.12, only the "asymmetric" keyType defines type-specific
+// restrictions.
+//
+// See the full documentation at:
