I think this is a reasonable idea. I'm hitting exactly the issue this series is trying to solve, Lee invested a lot of effort to make drivers/infiniband/ W=1 clean, but as maintainer I can't sustain this since there is no easy way to have a warning free compile and get all extra warnings. Also all my submitters are not running with W=1 I need kbuild to get everyone on the same page to be able to sustain the warning clean up. We've already had a regression and it has only been a few weeks :( Andrew, would you consider respinning this series in the above form? Thanks, Jason
