Subject: [GIT PULL] Btrfs fixes

Hi everyone,

The for-linus branch of the btrfs git tree:

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

Has our collection of bug fixes.  I missed the last rc because I thought
our patches were making NFS crash during my xfs test runs.  Turns out it
was an NFS client bug fixed by someone else while I tried to bisect it.

All of these fixes are small, but some are fairly high impact.  The
biggest are fixes for our mount -o remount handling, a deadlock due
to GFP_KERNEL allocations in readdir, and a RAID10 error handling bug.

This was tested against both 3.3 and Linus' master as of this morning.
