We followed storage_probe () almost completely, and it seems that everything is about to end, but do you think you haven't understood how the device works so far? USB flash drives are not only USB devices but also "disks". They also need to comply with the USB Mass Storage protocol and Transparent SCSI specifications. From the driver's perspective, it is similar

So here, we need to carefully check the path we have chosen. Obviously, we have already said that for a USB flash drive, spec specifies that it belongs to the bulk-only transmission mode, that is, its US-> protocol is us_pr_bulk. This is just determined in get_device_info. Therefore, in the entire switch section, we only ex

The following describes the usb_stor_control_thread () function. What wakes up is the up ( (us-> sema) from the queuecommand, and us-> sulfate is assigned to the Server Load balancer, in contrast, the Server Load balancer is a parameter passed in when the SCSI core layer calls the queuecommand. Focus on usb_stor_control_thread (). Row 3: As mentioned earlier, we have to look at the dev_mutex lock from a higher perspective after reading the entire module.
