Hi Anand,

Can you please post the patch in the body of the message so we can
comment on it inline.

Aditya is also working on a btrfs snapshots xfstest (currently named
257) as part of
his Google summer of code project.

It would be great if you guys can cooperate your efforts.

BTW, while running Aditya's test, Greg has stumbled upon a btrfs OOPS.
Greg can provide more details about it.

Cheers,
Amir.
