According to ntb_transport.c, the driver may sleep in interrupt handling.
The function call path is:
ntb_transport_rxc_db (tasklet_init indicates it handles interrupt)
   ntb_process_rxc
     ntb_async_rx
       ntb_async_rx_submit
         schedule_timeout --> may sleep

This bug is found by my static analysis tool and my code review.
I hope to fix it, but I do not have a good solution.

Thanks,
Jia-Ju Bai
