Subject: Re: Using parts of ext2_fs.h in BSD licensed code

Just found, that recently FreeBSD got this:
http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/fs/ext2fs/ext2fs.h
It looks like I can easily include it to the BSD-licensed project and
no GPL violation. But I dunno how did they wrote ext2fs.h, since it
still must be based on ext2_fs.h
