Hi,
I want to do this at the filesystem-level not in user-space.
I have a stackable-filesystem that runs as a layer on top of the
existing filesystem (with all the function pointers mapped to the
corresponding base filesystem function pointers, and other suitable
adjustments).
So yes I have access to the filesystem.
But the question is how can I access those particular data-blocks?

there is an ioctl to find the blocks the file is in.. but still that's
only a snapshot, not a guarantee. What you really need/want is to do
this at the filesystem level, you can't reliably do it above that level.
