Looks the previous patch still has the race problem, so could you just
apply the attachment patch and cancel all previous patches for the
test? If there is still the problem, please post out the log.

BTW, the attachment patch is only for verifying if the current problem
is caused by 'filp->private_data' race, and not for merge.

Thanks,
