OK, but in that case I'd like to see that one first,
then see what issues remain.

Stricter conformance to the mass storage class spec is the
reason for set_wedge().  This patch was described as aiding
such conformance.

Now, it's clear there is one inherent issue in the current
code:  no set_wedge().  My eventual eyeballing will be because
I suspect there may be other issues too.

See, I ran the USBCV tests last week -- not on file_storage,
just standard tests, on gadget zero -- and the current code
passed those just fine.  So to that extent, what's needed
is will be something specific to mass storage support.
