Miroslav Benes cba82dea30 livepatch: Send a fake signal periodically ... An administrator may send a fake signal to all remaining blocking tasks of a running transition by writing to /sys/kernel/livepatch/<patch>/signal attribute. Let's do it automatically after 15 seconds. The timeout is chosen deliberately. It gives the tasks enough time to transition themselves. Theoretically, sending it once should be more than enough. However, every task must get outside of a patched function to be successfully transitioned. It could prove not to be simple and resending could be helpful in that case. A new workqueue job could be a cleaner solution to achieve it, but it could also introduce deadlocks and cause more headaches with synchronization and cancelling.
