Shaui,

Sorry I didn't follow up on this part.  Yes, I'm happy to take your (excellent) changes.

I did a "git fetch" from your repo and the a "git merge" of all except the README and LICENSE
commits at the tip of your repo. Those I manually cherry-picked (since the last section of your
README said "clone of Tony's repo" ... which makes no sense in my repo).

Resulting tree has been pushed out to git://git.kernel.org/pub/scm/linux/kernel/git/aegl/ras-tools.git

Please check that I didn't break anything.

-Tony
