I got the following crash on one of my Ceph nodes this morning. I
don't know how to reproduce it yet; I was just wondering if it was a
known issue. This is with the latest kernel for Ubuntu 10.10.

Hello all, 
   I ran a modified version of the file system fuzzer (https://github.com/sughodke/fsfuzzer) for one of the projects I am working, and at one point I got a possible crash.
   I got the following trace on a device with a 32bit kernel 3.14. I have searched the Bugzilla for this issue, but I was unable to find it.

   I am unsure of the impact/severity of the issue, and since I do not have experience with BTRFS I was hoping someone from here can take a look at it.

Some information:

# uname -a 
Linux *** 3.14.0-*** SMP PREEMPT Mon May 12 09:06:16 PDT 2014 i686 GNU/Linux
# btrfs --version 
Btrfs v3.12

   Call trace below. If you need additional info, please let me know, and I will be glad to provide it to you, if possible.

Regards, 
   Alexandru Cornea

When I was unsuspending my notebook today btrfs suddenly crashed the 
kernel.  Unfortunately the only debug output I have are some pictures 
made with a shitty mobile phone camera. Maybe they're of some value for 
you anyway:  http://image.bayimg.com/eaodgaadc.jpg (1.3M, 5000x2500px)

I'm using Arch Linux, kernel 3.3.2, btrfs 0.19.
