hi all:
when I trace kernel driver source about usb scsi storage driver, I
have below 2 questions:
1. in sd.c -> static int sd_probe(struct device *dev)
we use below macro to get scsi_device.
struct scsi_device *sdp = to_scsi_device(dev);
take usb for example, is usb storage driver allocate memory for
scsi_device then calling sd_probe?
I am looking for usb_stor_probe1 and usb_stor_probe2 but not find
where it is.
2. at the end of sd.c -> sd_probe, why we call async_schedule_domain like below
async_schedule_domain(sd_probe_async, sdkp, &scsi_sd_probe_domain);
to finish scsi device initialization?
Couldn't we put what sd_probe_async directly in sd_probe?
is there any benefit to do so?
