Subject: Re: [PATCH -mm 0/5] LZO and swap write failure patches for -mm

Andrew, Andrian,

If you really have the opinion of not going for major cleanups,
optimizations outside of original LZO code (basically a fork), then
there is no point in me continuing this work.

If you think otherwise, please let me know and I will post a newer
version with improvements from all these feedback I got.

Thanks,
Nitin
