That one seems interesting as the lockd thread calls lots of sleeping functions as well as file lock code that takes the BKL again, both of which of course is not allowed when converting to a spinlock. I just attempted to blindly convert lockd to taking lock_flocks() in place of the BKL and releasing it where necessary, but quickly gave up because this seems rather pointless. It basically never does anything interesting between places where it would need to drop the lock.
