Subject: kernel/relay.c: change return type to vm_fault_t
X-Git-Tag: v4.19~775^2~13

kernel/relay.c: change return type to 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.
