        sys/fs/udf/udf_subr.c: revision 1.167

On switching from writing to reading explicitly synchronize the caches. It
isn't strictly needed but some devices in the wild will otherwise bluntly
ignore all reading commands resulting in a kernel and device lockup.

For bug-compatibility with Windows, the last VAT sector must be a multiple of
16/32 from the start of the track.  To allow for scratches, write out at least
a 32 pieces.
