From: Sebastian Andrzej Siewior <bigeasy@xxxxxxxxxxxxx> The atmdev_ops::send callback which calls tasklet_disable() is invoked with bottom halfs disabled from net_device_ops::ndo_start_xmit(). All other invocations of tasklet_disable() in this driver happen in preemptible context. Change the send() call to use tasklet_disable_in_atomic() which allows tasklet_disable() to be made sleepable once the remaining atomic context usage sites are cleaned up.
