orangefs: Adding new return type vm_fault_t
Use new return type vm_fault_t for fault handler. 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 the following commit 1c8f422059ae ("mm: change return type to vm_fault_t") Fixed checkpatch.pl warning.
