Yes, I also think so.
This patch is my first step.

My modification policy is as follows:

1. short term
 - To more stable BTRFS, the part that should be corrected is clarified. 
 - The panic is not done by the NULL pointer reference etc.

2. long term
ã- BUG_ON() is decreased by using the forced-readonly framework(already posted by Liu Bo),
    etc. 

Thanks,
Itoh
