This patch series fixes some warnings reported by sparse when building the btrfs module. It fixes two classes of warnings: address space warnings and lock context warnings. This didn't uncover any logical errors, but it reduces the noise when checking the source. There are a few less straightforward sparse warnings still remaining.
