[PATCH] fs: nfs: Adding new return type vm_fault_t

From: Souptick Joarder
Date: Mon Jul 02 2018 - 11:24:49 EST

Use new return type vm_fault_t for fault handler
in struct vm_operations_struct. For now, this is
just documenting that the function returns a
VM_FAULT value rather than an errno. Once all
instances are converted, vm_fault_t will become
a distinct type.

see commit 1c8f422059ae ("mm: change return type to
vm_fault_t") for reference.
