- Correct the layout of all header versions - make all them well-specified for any external event. As we don't have 1-byte or 2-byte wide fields, the 32-bit layout (historical one) has no extra padding, so we can safely add __attribute__((packed)). - Add detection and reading of the broken 64-bit COW format which has been around for a while - to allow safe migration to the correct 32-bit format. Safe detection is possible, thanks to some luck with the existing format, and it works in practice.

This is the minimal fix to make 64-bit UML binaries create 32-bit compatible COW files and read them. I've indeed tested that current code doesn't do this - the code gets SIGFPE for a division by a value read at the wrong place, where 0 is found.

Improve (especially for coherence) some prototypes, and return code of init_cow_file in error case - for a short write return -EINVAL, otherwise return the error we got!

Improve some error messages in the COW driver, and say V3, not V2, when talking about V3 format. Also resync with our userspace code utility a bit more.

After restoring the existing code, make it work also when included in kernelspace code (which isn't currently the case, but at least this will prevent people from "fixing" it as just happened). Whitespace is fixed in next patch - it cluttered the diff too much. Signed-off-by: NPaolo 'Blaisorblade' Giarrusso <blaisorblade@yahoo.it> Signed-off-by: NLinus Torvalds <torvalds@osdl.org>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
