No, Linux relies on the compiler to pack things like this together and

Yes we've a __packed macro, but the norm in the usb subsys seems to be to use
__attribute__ ((__packed__)), see include/[uapi/]linux/usb/*.h
That's different. Things under include/uapi are meant for use by
userspace programs, so they can't rely on kernel-internal things like
the __packed macro.
Right, but almost all headers under include/linux/usb/*.h also use the
long form.
