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 -> 1c8f422059ae ("mm: change return type to vm_fault_t") previously cxl_mmap_fault returns VM_FAULT_NOPAGE as default value irrespective of vm_insert_pfn() return value. This bug is fixed with new vmf_insert_pfn() which will return VM_FAULT_ type based on err. Signed-off-by: Souptick Joarder <[email protected]>
