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. Version 2 replaces an open-coded implementation of kernel_write in write_buf, doesn't touch unrelated style issues, and add's David's Reviewed-by. This patch series applies to 3.17-rc7.
