Subject: [PATCH] include: dax: new-return-type-vm_fault_t
Date: Wed, 20 Jun 2018 22:50:46 +0530
Message-ID: <20180620172046.GA27894@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.

commit 1c8f422059ae ("mm: change return type to vm_fault_t")
