Strangely, this commit causes a regression in Linus's tree right now. I can't really figure out what the regression is, only that this commit triggers a "large Android system binary" from working properly. There's no kernel log messages anywhere, and I don't have any way to strace the thing in the testing framework, so any hints that people can provide would be most appreciated. thanks, greg k-h
