Kashyap, Desai 1278b11f46 [SCSI] mpt2sas : Device removal algorithm in interrupt context only ... external host not connecting after controller reboot: The problem is : devices are not coming back after having the cable disconnected then reconnected. The problem is because the driver/firmware device removal handshake is failing. Due to this failure, the controller firmware is not sending out device add events when the target is reconnected. This is root caused to a race in the driver/firmware device removal algorithm. There is duplicate code in both interrupt and user context; where target reset is being issue from user context path while sas_iounit_control(OP_REMOVE) is being sent from interrupt context. An active target_reset will fail the OP_REMOVE. To fix this problem, the duplicate code has been removed from user context path.
