I would presume that O_BENEATH is one of the so-called "file creation
flags". See this paragraph of the DESCRIPTION:

In addition, zero or more file creation flags and file status
flags can be bitwise-or'd in flags. The file creation flags are
O_TMPFILE, O_TRUNC, and O_TTY_INIT. The file status flags are
all of the remaining flags listed below. The distinction between
these two groups of flags is that the file status flags can be
retrieved and (in some cases) modified; see fcntl(2) for details.

David, presuming this is correct (I can't see how O_BENEATH could be a
"file *status* flag"), your patch should also add O_BENEATH to the
list in that paragraph.
