/* * Unregister all algorithms associated with a crypto driver. * If there are pending sessions using it, leave enough information * around so that subsequent calls using those sessions will * correctly detect the driver has been unregistered and reroute * requests. * * XXX careful. Don't change this to call crypto_unregister() for each * XXX registered algorithm unless you drop the mutex across the calls; * XXX you can't take it recursively. */
