Subject: [BUG] ntb: Sleep in interrupt handling
Date: Thu, 01 Jun 2017 17:17:56 +0800 [thread overview]
Message-ID: <592FDBC4.9000406@163.com> (raw)
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
