There might be an miss understanding here. For instance in
drivers/usb/storage/unusual_devs.h we have an entry like:
|UNUSUAL_DEV( 0x03f0, 0x4002, 0x0001, 0x0001,
| "HP",
| "PhotoSmart R707",
| USB_SC_DEVICE, USB_PR_DEVICE, NULL, US_FL_FIX_CAPACITY),
|
That US_FL_FIX_CAPACITY is used later in scsiglue.c to set sdev->fix_capacity
which is then used by sd_read_capacity() to substract one sector from the
final size.
In ub I see ub_sync_read_cap() and I don't see a change. Was my wording wrong
or is this something else?
