Most things are already implemented, while working I looked through linux and hurd implementations, but didn't use anything from there (I just learned some internals of ext2) and read http://nongnu.org/ext2-doc/ (thus my implementation mostly based on ext2-doc). Flags, constants, data structures are available in ext2-doc and ext2_fs.h. As I understand GPL license I can't just take it from ext2_fs.h and use in BSD licensed code, since it violates GPL (it was confirmed on #gnu). Is it correct? From another hand code based on ext2-doc can't be called derivative work. Is there any other header similar to ext2_fs.h (or any documentation except nongnu.org/ext2-doc/)? Do you think I can ask copyright owners for permission to use constants(data structures) from ext2_fs.h? Can somebody please send me Remy Card's email (in sources it's incorrect)? -- Evgeniy Ivanov
