From 36f062042b0fd9f8e41b97a472f52139886ca26f Mon Sep 17 00:00:00 2001 From: Souptick Joarder Date: Tue, 21 Aug 2018 21:54:44 -0700 Subject: [PATCH] fs/proc/vmcore.c: use new typedef vm_fault_t 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 1c8f422059ae ("mm: change return type to vm_fault_t") for reference.
