Part of the reason I went the way you had done for ATA is to try and guarantee one and one only probe action at a time per nexus. > you are slightly changing semantics of device probe.

It is very important for ATA, as probe function > also initializes device, that is mandatory if probe is called as result > of device reset. SCSI devices probably don't need that initialization, > but what if probe was called due to inquiry change status received > during probe sequence running? Are you sure you won't loose events here? > >
