Jan, the patch is over current yours for_mm branch

Yep, i know it exceeds 80 column *but* it looks much better
in this way ;)

I think this patch is wrong. Right now it doesn't change anything, but in future
when someone will add support for writing UDF > 2.01 (and bump UDF_MAX_WRITE_VERSION)
it will break for filesystems written with udfrev >= 2.01 && udfrev < UDF_MAX_WRITE_VERSION.

well, if someone add support the writting UDF > 2.01 it will require
additional switches/analisys anyway and saving these hard-coded-numbers
would not help.

Yes, but these values don't correlate with UDF_MAX_WRITE_VERSION - it's
simple coincidence. If you really don't like these numbers add another
constant.
