UDF in kernel for 10.1?

Unpleasantly surprising, UDF filesystem is not supported by the kernel in 10.0. I have looked in /proc/filesystems k3b cannot write UDF filesystems to DVD. It says "cannot determine filesystem size". The udftools package is installed. Will 10.1 have UDF support? I can't check right now. UDF support is needed to write >2GB files to DVD.
