hi all:
below are call back functions of usb_storage_driver:
static struct usb_driver usb_storage_driver = {
.name = "usb-storage",
.probe = storage_probe,
.disconnect = usb_stor_disconnect,
.suspend = usb_stor_suspend,
.resume = usb_stor_resume,
.reset_resume = usb_stor_reset_resume,
.pre_reset = usb_stor_pre_reset,
.post_reset = usb_stor_post_reset,
.id_table = usb_storage_usb_ids,
.supports_autosuspend = 1,
.soft_unbind = 1,
};
my questions are:
1. where we register the us->suspend_resume_hook in usb_stor_suspend?
I grep the src, but cannot find where the callback is registered.
2. suppose we are doing the scsi read/write command and system
suddenly store to RAM/DISK, will that scsi command do?
Drop it or keep the unfinished part ?
if the later one, will driver redo all CBW, in/out data, CSW?
if the previous one, where we keep the record that this scsi command
is dropeed due to hibernate?
appreciate your kind help,
