    mm: page_mkwrite change prototype to match fault · c2ec175c
    Nick Piggin authored
    Change the page_mkwrite prototype to take a struct vm_fault, and return
    VM_FAULT_xxx flags.  There should be no functional change.
    This makes it possible to return much more detailed error information to
    the VM (and also can provide more information eg.  virtual_address to the
    driver, which might be important in some special cases).
    This is required for a subsequent fix.  And will also make it easier to
    merge page_mkwrite() with fault() in future.
