I am having a weird issue when reading virtual files.
In particular all files have the expected file size , but are filled with spaces instead of the expected data.
Furthermore i do not receive any callbacks.
Using process monitor the stack for a random read operation includes cbflt3.sys.
So my understanding is that for some reason the read callback is not called/dropped.

I am attaching an image showing the stack trace.
I also have highlighted a sequence of operations for a specific file.


Thank you
