I guess I should have said "developing" rather than "maintaining" for
fs/udf since it's clear that someone has been keeping it running in-tree.
I started with udftools from source forge and then discovered that the
kernel udf driver does not support fallocate() which I was hoping to use.

Thanks for the pointer to Jan Kara. I'll see how he feels about patches
from the wilderness.

Yes, that's where I started. The last release was 1.0.0b3 in 2004.
Which is what the Ubuntu 14.04LTS package reports as it's version too.

Yep, that's where my ~works came from.
Ah, thanks for the links. I'll pull them all together and see what's there.
