I'd suggest restricting the bisect to fs/ first, and if that comes up with something non-sensical, you can always use the good/bad data points for a whole tree bisect. One commit that you might want to try testing is b43d17f31^, and see whether that works. One potential commit that might be suspicious is b43d17f31 given the stack trace shows one process apparently waiting on PageWriteback. - Ted
