That commit _should_ have just moved code around with no actual semantic changes. Can you verify that undoing just that one commit makes current git (-rc9) work for you? Ie just try a git revert 266c2e0abeca649fa6667a1a427ad1da507c6375 on top of the current tree. I just want to check, because even after looking at that diff again, I'm not seeing what it could actually change. Linus
