Hi,

I would like to add 64 bit user data to ion allocated buffer. This data may be assigned during buffer allocation (passed as one of the ioctl parameters) and may be queried by fd representing the buffer or pfn.

Looks like may be useful in many use cases. 

Please, let me know what do you think.

Thanks,
Alexey
