Hello: A possibility of a dangling lock and eventually a deadlock can occur in function [fnic_handle_fip_timer] on [v4.3-rc1].
Github Link: https://github.com/torvalds/linux/blob/v4.3-rc1/drivers/scsi/fnic/fnic_fcs.c#L1267 The lock acquired at line 1284 will not be unlocked upon function's exit if (vlan->state) value is (FIP_VLAN_AVAIL) when entering the switch statement at line 1298. A possible fix is to add a default case to the switch block or add a special case to handle the case where vlan->state) value is (FIP_VLAN_AVAIL).
