Subject: [GIT PULL v2] Update LZO compression

Hi all,

as suggested on the mailing list I have converted the updated LZO
code into git, so please pull my "lzo-update" branch from

  git://github.com/markus-oberhumer/linux.git lzo-update

You can browse the branch at

  https://github.com/markus-oberhumer/linux/compare/lzo-update

I'd ask some official kernel maintainer for review and to push this into
linux-next so that it will hopefully land in the 3.7 release.

Share and enjoy,
Markus
