As I understood, we would also need to specify the beginning of the slice
relative to the beginning of the start code so we don't have to assume
fixed-size start codes or have to do the parsing in the kernel.
This can certainly be done as a subsequent patch/series, and definitely not
necessarily by you (don't want to add more on your shoulders at this point)!
Cheers,
