[CRIU] multiple img files

[Sanidhya Kashyap]

Hi,

I wanted to know why do we have multiple img files for dumping and
restoring the data using criu.

What will happen if we used a single file to dump everything instead
of multiple files?

Is there a case that the criu code might be writing / reading the data
to / from multiple files simultaneously?

Thanks,
Sanidhya
