This contains LZO1X-1 compressor and LZO1X decompressor (safe and

I understand that the 'safe' decompression code is 'somewhat slower' and that decompressor performance is a key feature of this algorithm. However, I am concerned about the safety implications of including the 'unsafe' standard version in-kernel when likely uses include compression of network data, memory objects and so-on, all of which could in theory be maliciously modified.

I'm no kernel or programming expert, so I may be off the mark with this one. To me, at least, even if the answer is 'no, there isn't a problem' that's still a valuable clarification :)

Thanks,
