Maybe and ioctl to turn on partition scanning if it is currently disabled
or return an error otherwise would be the better thing? It would
do the right thing for the most common loop case, and with a bit more
work could do the right thing for those that more or less disable it
graciously (ubiblock, drbd, zram) and would just fail for those who are
so grotty old code and slow devices that we never want to do a partition
scan (basically old floppy drivers and the Nintendo N64 cartridge driver)
