Jan Kara maintains UDF, and I'm not aware of any outstanding problems or patches that are unduly delayed. Sure, there's not a huge flux of patches, but that's to be expected, I think.

It'd be nice if it were converted to use iomap instead of buffer_heads. If anyone's looking for a filesystem project ...

The main reason for not using UDF as a data exchange format is not the Linux support in my eyes, but the rather non-optimal support on other platforms. Reading from UDF works on other platforms from my experience, but in the past I've had trouble writing to UDF filesystems on Windows - sometimes it just didn't work, with no apparent reason for the failure.

UDF is nice in theory, but in practice exFAT is probably what's here to stay for simple data exchange.
