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