Oops with kernel 3.3-rc7

Hello All,
	I have had another oops to report.  I am using btrfs as my root file
system.  It was originally ext4 that I converted to btrfs.  I also
had /home on a separate partition but deleted it and extended my root
partition then grew the root file system with "btrfs filesystem resize"
My /boot partition is ext2.  Please feel free to email me with any
questions.  

TIA -- Nate

There have been patches submitted to fix this already.  I believe we're
waiting on Jens to push them to Linus.  You can find them here:

http://git.kernel.org/?p=linux/kernel/git/axboe/linux-block.git;a=shortlog;h=refs/heads/for-linus

Jens, is there some reason you haven't pushed those yet?
