From 8bf782f64737be055e6c1fad7a4c7cae7aae2d99 Mon Sep 17 00:00:00 2001 From: Souptick Joarder Date: Fri, 29 Jun 2018 00:12:40 +0530 Subject: [PATCH 1/2] orangefs: Adding new return type 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. See the following commit 1c8f422059ae ("mm: change return type to vm_fault_t") Fixed checkpatch.pl warning.
