Revision 32c37fc30c52508711ea6a108cfd5855b8a07176 authored by Oliver Neukum on 14 October 2013, 13:24:55 UTC, committed by Greg Kroah-Hartman on 16 October 2013, 20:32:04 UTC
Some USB drive enclosures do not correctly report an
overflow condition if they hold a drive with a capacity
over 2TB and are confronted with a READ_CAPACITY_10.
They answer with their capacity modulo 2TB.
The generic layer cannot cope with that. It must be told
to use READ_CAPACITY_16 from the beginning.
