infiniband: hw: hfi1: Change return type to vm_fault_t (d8197341) · Commits · 戴 / test

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. Reference id -> ("mm: change return type to vm_fault_t") Signed-off-by:
