There's no secret sauce in the internal tree, it's just that I backport everything into the 5.2 version that is our newest. It's fully uptodate with 5.4-rc and in some cases what's queued up for 5.5 as well. Hence I sometimes forget to check what is applicable to 5.3-stable, since I have it in our 5.2 tree... The internal tree is just backports. That's how we do things. -- Jens Axboe
