Subject: [PATCH v2] misc: sgi-gru: Change return type to vm_fault_t
Date: Wed, 25 Apr 2018 10:20:44 +0530 [thread overview]
Message-ID: <20180425045044.GA21558@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.
