[GIT PULL] Btrfs

Hi Linus,

Please pull my for-linus branch:

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

This is based on 3.17-rc5 because that's when I forked off for -next,
but I've been testing it against linux-next or 3.17 for a while now.

The largest set of changes here come from Miao Xie. He's cleaning up
and improving read recovery/repair for raid, and has a number of related

I've merged another set of fsync fixes from Filipe, and he's also
improved the way we handle metadata write errors to make sure we force
the FS readonly if things go wrong.

Otherwise we have a collection of fixes and cleanups. Dave Sterba gets
a cookie for removing the most lines (thanks Dave).
