I got below oops when doing file write with mount option max_extent=1M
It appears the accouting is already done in set/clear/split/merge hooks and
I don't see reason why we need do accouting in __btrfs_remove_ordered_extent
again. Below patch makes my test work but please double check.

I believe there is a kerneloops associated with this problem:

Greetings!
I have a singe 2TB disk formatted with btrfs 0.19 on Ubuntu 10.04-alpha2:
# uname -a
Linux fan-ting 2.6.32-14-generic #20-Ubuntu SMP Sat Feb 20 05:18:19
UTC 2010 x86_64 GNU/Linux
# df -h /media/onlyhope/

Hi,
in a long overdue followup to my previous email, I am sending a patch
that modifies the result of running 'df' against a btrfs volume. I
understand that, give the simplicity of 'df', there is not 'correct'
solution - I do think however, that the changed output is more
intuitive. Most important
