Darwish The usage of in_interrupt() in drivers is phased out and Linus clearly requested that code which changes behaviour depending on context should either be separated or the context be conveyed in an argument passed by the caller, which usually knows the context. usbip_recv() uses in_interrupt() to conditionally print context information for debugging messages. The value is zero as the function is only called from various *_rx_loop() kthread functions. Remove it. Signed-off-by: Ahmed S.
