[GIT PULL] Btrfs

From: Chris Mason
Date: Tue Jul 09 2013 - 15:19:00 EST

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):

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

I did it this way because the 3.10 merge was pretty much empty and you
probably don't want my merge commit at the top.

There's a trivial conflict with your current master involving a printk spelling
fix, but these are otherwise clean and tested against your current tree.

These are the usual mixture of bugs, cleanups and performance fixes. Miao has
some really nice tuning of our crc code as well as our transaction commits.

Josef is peeling off more and more problems related to early enospc, and has a
number of important bug fixes in here too.

The stats below are against my for-linus branch.
