[PATCH 0/1] MR7769: ntdll: correctly detect the NUL device under macOS

[John Szakmeister (＠jszakmeister)]

macOS doesn't have a way to detect this via the FIODTYPE ioctl(), so we have to resort to detecting
the NUL device via major and minor version number.  Fortunately, that hasn't changed since the
inception of macOS.
