[GIT PULL] Btrfs

[Chris Mason]

Hi Linus,

My for-linus-4.7 branch has some fixes:

git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs.git for-linus-4.7

I realized as I was prepping this pull that my tip commit still had
Facebook task numbers and other internal metadata in it.  So I had to
reword the description, which is why it is only a few hours old.  Only
the description changed since testing.

The important part of this pull is Filipe's set of fixes for btrfs device
replacement.  Filipe fixed a few issues seen on the list and a number
he found on his own.
