Previously vm_insert_page unable to return VM_FAULT_ type due to which different drivers have their own mapping from err to VM_FAULT_ type. With new vmf_insert_page() introduce in 4.17-rc1 we have a common mapping for err to VM_FAULT_ which remain same for every drivers/file systems.
Was this previously wrong?
I think Matthew is the right person to answer this.
