From 2bcd6454bae78775632e1848ce1eabf65c6fbd4f Mon Sep 17 00:00:00 2001 From: Souptick Joarder Date: Thu, 7 Jun 2018 17:08:00 -0700 Subject: mm: use new return type 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.
