From 50a7ca3c6fc86955f99fc432fc8a186b968b365b Mon Sep 17 00:00:00 2001 From: Souptick Joarder Date: Fri, 17 Aug 2018 15:44:47 -0700 Subject: mm: convert return type of handle_mm_fault() caller to 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. Ref-> commit 1c8f422059ae ("mm: change return type to vm_fault_t") In this patch all the caller of handle_mm_fault() are changed to return vm_fault_t type.
