I will sum up the last four patches of this series by saying that they
add features for emulating DVD-ROM and BD devices. Doing so increases
the size of the f_mass_storage driver by a considerable amount and
also adds a large amount of new material to Jens Axboe's
include/uapi/linux/cdrom.h.
Is any of this really needed? What usage scenarios require
f_mass_storage to emulate a DVD-ROM that couldn't use f_tcm instead?
