The plan for these patches is to introduce the typedef, initially just as
documentation ("These functions should return a VM_FAULT_ status").  We'll
trickle the patches to individual drivers/filesystems in through the
maintainers, as far as possible.  Then we'll change the typedef to an
unsigned int and break the compilation of any unconverted

The return value of page_mkwrite defined in vm_operations_struct has
changed to vm_fault_t type. So this patch is part of patch series which will
convert fault handlers for vm_operations_struct in each driver/file system.

The first patch is already merged into linus tree.

What is the target tree to carry this?

Target tree I am not sure.
We have plan to push it in 4.17 release.
I think Matthew is the right person to get this info.
