Subject: [PATCH v3] videobuf: Change return type to vm_fault_t
Date: Thu, 19 Apr 2018 00:17:16 +0530 [thread overview]
Message-ID: <20180418184716.GA25507@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.
Reference id -> 1c8f422059ae ("mm: change return type to
vm_fault_t")
