    ntfs: Use ERR_CAST() to avoid cross-structure cast · fee2aa75
    Kees Cook authored
    When trying to propagate an error result, the error return path attempts
    to retain the error, but does this with an open cast across very different
    types, which the upcoming structure layout randomization plugin flags as
    being potentially dangerous in the face of randomization. This is a false
    positive, but what this code actually wants to do is use ERR_CAST() to
    retain the error value.
