I haven't had time to look in details yet but in that context, what does
"vma" stands for ? There's already an important vm data structure in
linux routinely called "vma" and thus I suspect this is a poor naming
choice as it will cause confusion.
Cheers,
Ben.

It looks like it actually is dealing with vma to me. But then again:
- please don't use typedefs for structures
- there might be a more descriptive name for this than just vma_map

Yes, I'll come up with some (hopefully) better name.
