Duoming Zhou fa59d49a49 qlcnic: fix sleep-in-atomic-context bugs caused by msleep ... [ Upstream commit 8dbd6e4ce1b9c527921643d9e34f188a10d4e893 ] The watchdog timer is used to monitor whether the process of transmitting data is timeout. If we use qlcnic driver, the dev_watchdog() that is the timer handler of watchdog timer will call qlcnic_tx_timeout() to process the timeout. But the qlcnic_tx_timeout() calls msleep(), as a result, the sleep-in-atomic-context bugs will happen. The processes are shown below: (atomic context) dev_watchdog qlcnic_tx_timeout qlcnic_83xx_idc_request_reset qlcnic_83xx_lock_driver msleep --------------------------- (atomic context) dev_watchdog qlcnic_tx_timeout qlcnic_83xx_idc_request_reset qlcnic_83xx_lock_driver qlcnic_83xx_recover_driver_lock msleep Fix by changing msleep() to mdelay(), the mdelay() is busy-waiting and the bugs could be mitigated.
