Hi Linus,
Please pull my for-linus-4.5 branch:
git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs.git

Hi Linus,
My for-linus-4.5 branch has a btrfs DIO error passing fix. I know how
much you love DIO, so I'm going to suggest against reading it. We'll
follow up with a patch to drop the error arg from dio_end_io in the
next merge window.

These are mostly fixes that we've been testing, but also we grabbed and
tested a few small cleanups that had been on the list for a while.

Hi Linus,
This Btrfs pull is available in two flavors:
First, my for-linus branch has it against all the btrfs pulls from 3.10:
git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs.git for-linus
Or, with a merge commit on top of 3.10 (master branch):
Hi Linus,
Please pull my for-linus branch:

I've merged my for-linus up to 3.12-rc3 because the top commit is only
meant for 3.12. The rest of the fixes are also available in my master
branch on top of my last 3.11
