The aacraid driver invokes scmd->scsi_done(scmd) for two types of SCSI
commands:
- SCSI commands initialized by the SCSI mid-layer.
- SCSI commands initialized by aac_probe_container().
The processing sequence for SCSI commands allocated by
aac_probe_container() is as follows:
aac_probe_container()
-> _aac_probe_container(scmd, aac_probe_container_callback1)
-> scmd->SCp.ptr = aac_probe_container_callback1
-> aac_fib_send(..., _aac_probe_container1, scmd)
-> fibptr->callback = _aac_probe_container1
-> fibptr->callback_data = scmd
fibptr->callback(scmd)
-> _aac_probe_container1(scmd, fibptr)
[ ... ]
-> _aac_probe_container2(scmd, fibptr)
-> Call scmd->SCp.ptr == aac_probe_container_callback1
-> scmd->device = NULL;
The processing sequence for SCSI commands allocated by the SCSI mid-layer
if _aac_probe_container() is called is as follows:
aac_queuecommand()
-> aac_scsi_cmd()
-> _aac_probe_container(scmd, aac_probe_container_callback2)
-> scmd->SCp.ptr = aac_probe_container_callback2
-> aac_fib_send(..., _aac_probe_container1, scmd)
fibptr->callback(scmd)
-> _aac_probe_container1(scmd, fibptr)
[ ... ]
-> _aac_probe_container2(scmd, fibptr)
-> Call scmd->SCp.ptr == aac_probe_container_callback2
Preserve the existing call sequences by calling scsi_done() for commands
submitted by the mid-layer or aac_probe_container_scsi_done() for commands
submitted by aac_probe_container().
