Subject: [PATCH v2] ipc: Adding new return type vm_fault_t
Date: Wed, 25 Apr 2018 10:04:13 +0530	[thread overview]
Message-ID: <20180425043413.GA21467@jordon-HP-15-Notebook-PC> (raw)

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.
