No, Noone from the kernel answered. And I'm sorry, but I'm not sure
what is going on in the code, so I don't want to close this here by just
removing those flags from the manual page, because I worry that the
actual code may be wrong or something. So I prefer that when Michael
has some time he can maybe review this and say something. Ideally,
someone from the kernel would also respond, but they haven't. I've CCd
the LKML; let's see if someone reads this and can help.
Thanks,
Alex
P.S.: Please, if we haven't responded in a month from now, ping us
again. Thanks again.
