From 9ee84466b7130360d07241baf4c95a553fc0a997 Mon Sep 17 00:00:00 2001 From: Souptick Joarder Date: Sat, 21 Apr 2018 01:15:24 +0530 Subject: [PATCH] fs: kernfs: Adding new return type vm_fault_t Use new return type vm_fault_t for page_mkwrite and 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.
