    mm: Change return type int to vm_fault_t for fault handlers · 2b740303
    Souptick Joarder authored
    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.
    
    Ref-> commit 1c8f4220 ("mm: change return type to vm_fault_t")
    
    The aim is to change the return type of finish_fault() and
    handle_mm_fault() to vm_fault_t type.  As part of that clean up return
    type of all other recursively called functions have been changed to
    vm_fault_t type.
    
    The places from where handle_mm_fault() is getting invoked will be
    change to vm_fault_t type but in a separate patch.
    
    vmf_error() is the newly introduce inline function in 4.17-rc6.
