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_CLOEXEC, O_CREAT, O_DIRECTORY,  O_EXCL,  O_NOCTTY,  O_NOFOLLOW,
       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.

Cheers,

Michael
