ACK

I take it the checking for FS_DRIVER_TYPE_LOOP in the first loop is just
an optimization (or sanity check) over making more calls and determining
the same thing.  IOW previous the first loop didn't care about fsdriver
type before making the SetupLoopDeviceFS call, but that could fail if it
wasn't a loop device.
