    iov_iter: Turn iov_iter_fault_in_readable into fault_in_iov_iter_readable · a6294593
    Andreas Gruenbacher authored
    Turn iov_iter_fault_in_readable into a function that returns the number
    of bytes not faulted in, similar to copy_to_user, instead of returning a
    non-zero value when any of the requested pages couldn't be faulted in.
    This supports the existing users that require all pages to be faulted in
    as well as new users that are happy if any pages can be faulted in.
    
    Rename iov_iter_fault_in_readable to fault_in_iov_iter_readable to make
    sure this change doesn't silently break things.
