I added a macro by which you can query an iterator to find out how the

linux/uio.h.
I'd support moving FOLL_* definitions to mm_types.h along with
FAULT_FLAG_* and VM_FAULT_*.
+1, great idea. The use of FOLL_* without including it's .h directly was
the first thing that jumped out at me when I just started looking at
this. And these really are mm types, so yes.
