From 14f28f5776927be30717986f86b765d49eec392c Mon Sep 17 00:00:00 2001 From: Souptick Joarder Date: Thu, 14 Jun 2018 15:27:55 -0700 Subject: [PATCH] ipc: use 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.
