According to fc_disc.c, the driver may sleep under a RCU lock, and the function call paths are: fc_disc_done (acquire the RCU lock) fc_rport_logoff mutex_lock --> may sleep
fc_disc_done (acquire the RCU lock) fc_rport_login mutex_lock --> may sleep
fc_disc_stop_rports fc_rport_logoff mutex_lock --> may sleep
These bugs are found by my static analysis tool and my code review.
Thanks, Jia-Ju Bai
