Btrfs updates

Hi Linus,

My for-linus branch has btrfs fixes and updates:

git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs.git for-linus

The top commit is the only one that isn't strictly a bug fix. It updates the btrfs metadata checker code to support metadata blocks larger than the page size. This code isn't compiled in by default, and it is only used by developers. I put it at the top so you could just peel it off if you didn't want it. I also put a for-linus-min branch without this commit:

git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs.git for-linus-min

The others are pure bug fixes. We have a use-after-free in there, along with errors when mount -o discard is enabled, and a BUG_ON(we should compile with UP more often).
